Sunday, March 22, 4:30 p.m.–7:30 p.m.
Category C. Optical Devices for Switching, Filtering and Signal Compensation
OSuE, Can Integrated Photonics Enable Optical Interconnection Networks in Advanced Computing and Network Systems? Yurii Vlasov¹, Keren Bergman², Ashok Krishnamoorthy³; ¹IBM, TJ Watson Res. Ctr., USA, ²Columbia Univ., USA, ³Sun Microsystems Inc., USA. With computer systems performance soon to approach Exaflop/s a dramatic increase in communications bandwidth for shuttling ExaBytes/s of data across the system, between the racks, chips and cores is becoming a major challenge. Optical interconnects already started to penetrate the computing communications infrastructure and are destined to make further inroads at all levels. Within just a few years it is expected that the number of optical links in a single computer system will become comparable with the total number of optical telecommunications links installed all over the world. The workshop will explore how recent advances in nanoscale silicon photonic technologies might be exploited for developing optical interconnection networks that address the critical bandwidth and power challenges presented across several levels of the computing system interconnect.
Questions:
(Systems Perspective)
- What are the major interconnect-centric challenges to future Exascale computer systems?
- What is your vision for how/when optical interconnects may be employed at various levels (system, racks, boards, on-chip)? what are the corresponding relevant benchmarks (Tbp/s, mW/Gbps, $/Gbps)?
- Are there any architectural or system/applications performance benefits to using optics? what critical challenges must be addressed? how would optical technologies be used in complement to electronics?
(Device Technology Perspective)
- What are the major device integration, packaging, manufacturing, etc. challenges to inserting nanoscale silicon photonic based optical interconnects?
- What is your vision on the optimal level of integration (on-board, on-multi-chip-carrier, on-chip, CMOS integrated)?
- What are the critical engineering constraints and trade-offs of bringing optics to a chip-scale level (temperature, loss, footprint, power, integration level,...)? what are some of the fundamental limitations of nanophotonic components (modulators, receivers, switches, WDM etc.)?

OSuA, Electronic Signal Processing and the Design of Optical Transport Systems, Doug McGhan¹, Peter Winzer²; ¹Nortel, Canada, ²Bell Labs, Alcatel-Lucent, USA. This workshop will address system-level implications of digital signal processing (DSP) in high bit rate (>40 Gb/s) transponders. Carrier requirements and expectations will be discussed, such as the increasing need for spectral efficiency at sufficient transparent reach and at a reduced cost per bit, line system design and management complexity, implications of fiber quality on route planning, provisioning, performance monitoring, and expectations on a system's error and outage performance. These carrier views will be contrasted with system vendors' perspectives, including realistic transponder hardware implications (power consumption, footprint, scalability), implications of fiber nonlinearity, aspects of upgradability, and the co-existence of wavelengths at different bit rates. Furthermore, the interface between vendors and carriers regarding performance prediction and verification for systems relying heavily on DSP will be discussed. Download Workshop Agenda.
Category G. Optical Processing and Analog Subsystems
OSuC,Present and Future Applications of Analogue Microwave Photonics, Ernesto Ciaramella¹, Idelfonso Tafur-Monroy², Thomas Clark³; ¹Scuola Superiore Sant'Anna, Italy, ²Denmark Technical Univ., Denmark, ³JHU Applied Physics Lab, USA. Photonics may be even more suited for analog than for digital signal applications. Today, microwave photonics techniques are currently used in radio-over-fibre signal transmission and other commercial applications, but recent advances are widening the scope of application to new areas. The speakers will introduce present and emerging opportunities for analog photonics, among which microwave filters, arbitrary optical waveform control, THz radiation and UWB pulse generation. A panel discussion will contrast different views from company, academy and funding bodies, to identify the most promising ones for commercial applications as well as the challenges and research opportunities to be pursued to make it reality.

Category H. Core Networks
OSuB, Energy Footprint of ICT: Forecast and Network Solutions, Patrick Leisching¹, Mario Pickavet²; ¹Nokia-Siemens Networks, Germany, ²Ghent Univ., Belgium. ICT provides many energy-saving solutions, but is also responsible for a considerable and quickly increasing energy footprint on its own. Recent surveys estimate that the complete life-cycle of ICT equipment today is responsible for about 4% of the worldwide primary energy consumption. This percentage is expected to double within 10-15 years, if current ICT energy trends are not drastically deviated.
This workshop will provide insight in the main ICT energy consumption factors and their expected future evolution in transport networks, highlighting access, metro and core networks and server farms. Possible research directions and future network paradigms will be outlined, motivated and elaborated by expert speakers from industry and academia. Special attention will be paid to the role of optics. A closing panel discussion will identify key research challenges and action points.
Category I. Access Networks
OSuD, Migration Scenarios toward Future Access Networks I, Leonid Kazovsky¹, Kent G. McCammon²; ¹Stanford Univ., USA, ²Access Technologies, AT&T Labs, USA.
OMD, Migration Scenarios toward Future Access Networks II, Leonid Kazovsky¹, Kent G. McCammon²; ¹Stanford Univ., USA, ²Access Technologies, AT&T Labs, USA. Future broadband access networks are likely to be quite different from those we’re familiar with today. Most probably, they will consist of a fiber backbone and wireless “end links” to individual users. Thus, realistic, cost-effective migration scenarios for convergence of optical and wireless networks will be needed. The fiber backbone is likely to be highly flexible, dynamic, adaptive to traffic, and based on both TDM and WDM technologies. So, realistic migration scenarios from TDM toward hybrid TDM/WDM or even "pure" WDM will be needed. The wireless “end links” are likely to be based on a derivative of Wi-Fi, Wi-Max, or 3G cellular networks.These networks can evolve through several possible avenues including carrier-based PONs or hybrid fiber/coax networks; cell telephone networks; or their combinations. This evolution will require a significant R&D effort and major intellectual and financial investment, perhaps more significant than the investment that went into wide-area networks. It will also require new components, architectures and algorithms. This workshop will examine possible structure of future broadband access networks, likely evolution scenarios, and R&D issues that will need to be addressed to make the new networks a reality.

NFOEC 1: Optical Networks and Services
NSuA, Optical and Packet Control Planes: Convergence or Divergence? Lyndon Y. Ong; Ciena Corp., USA. Two major developments are impacting carrier transport networks: the first is the emergence of the optical control plane, applied initially to TDM and now to all-optical networks. The second is the evolution of packet control planes, especially Ethernet, towards control by routing protocols (PLSB) and towards connection-oriented services (PBB-TE and MPLS-TP). How do these developments compare and what are the key issues? For example, all-optical networks may require greater complexity and overloading of the control plane – is distributed or centralized path computation the right model? Packet networks are expected to offer multipoint as well as point-to-point services – is the functionality provided by control plane protocols a good fit? Finally, what developments have been made in bodies such as IETF, OIF and ITU-T and in the research community to support interaction between optical and packet layers through a multi-layer control plane? This workshop will explore the current state of work on optical and packet control planes, and the potential for multi-layer convergence.

Category B. Fiber and Waveguide-Based Devices: Amplifiers, Lasers, Sensors and Performance Monitors
OMF, Size Matters--Breaking the Limits of High-Power Fiber Lasers, Johan Nilsson¹, Siddharth Ramachandran²; ¹Univ. of Southampton, UK, ²OFS Labs, USA. One of the hottest areas of growth in photonics outside of telecom is fiber lasers. This is fueled by diverse applications ranging from the materials processing and defense industries, to biomedical tools. Single-mode Yb-doped fiber lasers are now approaching 10 kW of output power, but recent estimates suggest that we may be running into fundamental scalability limits. This workshop will address this issue, and in particular, explore and debate the path-breaking technologies that fuel the recent dramatic advances in fiber lasers. Specific topics to be addressed include, but are not limited to:
- Why fiber lasers, in the first place? Wavelengths, pulsewidths, linewidths, etc.
- Core area scaling.
- Influence of materials, dopant concentrations, photodarkening, etc.
- Amplifier architectures and coherent combination techniques that enable power scaling.
Robust debate on these topics is anticipated, and potential participants are encouraged to submit ideas for presentation (5-10 min. slots). Such suggestions should be emailed to Johan Nilsson (jn@orc.soton.ac.uk) or Siddharth Ramachandran (sidr@ieee.org) by February 10, 2009.

Category D. Optoelectronic Devices
OMA, 100 Gb/s for $100, Bryan S. Robinson¹, Clint Schow²; ¹MIT Lincoln Lab, USA, ²IBM T.J. Watson Res. Ctr., USA. Performance gains in computer systems are increasingly achieved through interconnecting large numbers of parallel processor nodes. The resulting demands on communication bandwidth are challenging, with the computer backplane or the telecom terminal backplane looming as one of the primary bottlenecks to information transfer. Cost analysis places the break-even point for a compelling business case at $1 per Gbit/s. This workshop will cover several distinct approaches that address the backplane problem by displacing conventional copper with optical interconnects to meet future inter- and intra-rack bandwidth demands. A panel discussion will contrast the proposed approaches to identify the device technologies with the most promise to enable massive amounts of short-reach interconnect bandwidth at low-cost, with low-power consumption, a high area density, and potential for future scalability.
Category F. Transmission Subsystems and Network Elements
OMB, Single-Carrier Versus Multiple-Carrier Modulation Formats for WDM Systems, Henning Bülow¹, Sander Jansen²; ¹Alcatel-Lucent, Germany, ²Nokia Siemens Networks GmbH & Co. KG, Germany. New modulation schemes are being proposed to further mine the transmission bandwidth enabled by optical fiber and increased spectral efficiency. Two broad categories are emerging: single carrier and multiple carrier formats. Currently discussed approaches range from multi-level phase or amplitude modulation to optical OFDM, respectively. This workshop should explore pros and cons of the two approaches, including cost and realization aspects, performance over installed base, operational aspects, network availability, and ultimate spectral efficiency.

Introduction of the Workshop and an Overview on 100GbE Approaches |
| 8:14 a.m.– 8:32 a.m. |
The "Five Ws" of 100G,Jim King, AT&T, USA. This talk will describe a carrier's view of the emergining 100G market, providing answers to the standard "Five W" questions (Who, What, Where, When, and Why) for this technology. The answers will be drawn from parallels learned from AT&T's leadership in 40G development / deployment. |
| 8:32 a.m.– 8:50 a.m. |
The Strength of One, Kim Roberts, Nortel, Canada. One carrier, modulated at the highest baud rate where a CMOS A/D can provide Nyquist sampling, will produce the best cost/performance in spectrally constrained single mode applications. The Optical-OFDM class of processing is better applied to multimode fiber. At the other extreme, myriad parallel incoherent optical carriers per signal are more useful in unamplified fibers where spectral efficiency does not dominate system costs. |
| 8:50 a.m.– 9:08 a.m. |
No-Guard-Interval Coherent Optical OFDM for High Speed Optical Transport Networks, Akihide Sano and Yutaka Miyamoto, NTT, Japan. No-guard-interval coherent optical OFDM transmission scheme is attractive because of its compact signal spectra and high speed operation. We review its system configuration and transmission performances. |

Break |
| 9:28 a.m.– 9:46 a.m. |
O-OFDM Systems, Fred Buchali, Bell Labs, Alcatel-Lucent, Germany. OFDM was recently introduced to fiber optical communication and fundamentals and several advantageous characteristics will be demonstrated. Especially the influence of signals peak to average power ratio on system performance will be discussed in detail leading to a high robustness against fiber nonlinearities in non dispersion managed fiber links. |
| 9:46 a.m.– 10:04 a.m. |
Equalizer Complexity in Single and Multi-Carrier Coherent Optical Communications System, Bernhard Spinnler, Nokia Siemens Networks, Germany. Even though high speed electronics has made tremendous progress in terms of available processing power, the speed and implementable amount of digital logic still puts an upper limit on the complexity of digital signal processing algorithms. We investigate options for equalization in coherent optical communications systems and compare them in terms of complexity. We cover both single and multi carrier solutions with training and blind adaptation. |
| 10:04 a.m.– 10:22 a.m. |
Key Technologies and Innovations for Next Generation 40G and 100G Optical Interfaces, Christoph Schulien, CTO, CoreOptics,Germany. Next generation electro-optical transmission interfaces for the core network employ higher level modulation formats like QPSK, n-QAM or OFDM in conjunction with polarization multiplexing and coherent detection. The related subsystem architectures require advances on multiple fronts in photonics and high-speed electronics technologies and components. At the same time a minimum amount of standardization will be necessary to justify investment in these technology innovations. This contribution will address these aspects specifically from a subsystem provider's prospective. |
| 10:22 a.m.– 10:40 a.m. |
Soft Decision FEC for Single/Multi-Carrier Modulation, Takashi Mizuochi, Mitsubishi Electric,Japan. Codes, OH rate, and expected gain for soft-decision FEC in single-carrier/multiple-carrier modulation are discussed. A trial for hardware emulation of 100Gbps FEC is presented. |

Category J. Network Experiments and Non-Telecom Applications
OMC, Grid vs Cloud Computing and Why This Should Concern the Optical Networking Community, Chunming Qiao¹, Dimitra Simeonidou², Bill St. Arnaud³, Peter Tomsu4; ¹SUNY at Buffalo, USA, ²Univ. of Essex, UK, ³Canarie Inc., Canada, 4Cisco Systems Ltd., USA. Recently, there has been a lot of interests in Cloud, Grid and Utility computing and their influence in shaping the future network infrastructure. While Grid Computing is geared mainly towards scientific users and Grids, both Cloud and Utility computing are for enterprises. The common point for both approaches is their reliance on high speed optical networks to provide advanced and flexibly reconfigurable infrastructure. Optical network researchers are facing big challenges in delivering the necessary technologies for supporting Cloud, Grid and Utility computing services. Such technologies and services will change the Internet in much the same way as distributed and parallel computing has changed the computation and cyber-infrastructure today. The workshop will discuss various Cloud, Grid and Utility Computing approaches and will present the challenges (research and implementation) for our community.

NFOEC 2: Network Technologies
NTuD, Deployment of New Fiber Types, Sergey Ten; Corning Inc., USA.
In the last five years the telecommunications industry witnessed the development of new optical fiber types for networks ranging from short distance access networks to transoceanic links. Evolving technical and deployment requirements of modern networks led to the proliferation of fibers with optimized attributes that were later formalized into distinct fiber standards. Will the trend continue or have all of the fiber types needed for the various networks been invented? This workshop will review the drivers for the deployment of new fiber types in the past and will examine the requirements of future networks. It will feature the “cross examination” of the subject by network operators, system houses and fiber manufacturers.
Wednesday, March 25, 1:00 p.m.–3:00 p.m.
NFOEC 1: Optical Networks and Services
NWB, Emerging Carrier Optical Services, Vishnu S. Shukla; Verizon Communications, USA. Optical Transport Networks are undergoing a critical transition in which the network is migrating from a static legacy SONET/SDH-based transport to a dynamic intelligent Optical Transport Network (OTN). The driving forces behind this transition are the need to improve operational efficiency and to deploy more cost-effective optical transport than the existing ring-based infrastructure. There is growing customer demands for more bandwidth, faster provisioning, and richer sets of service functionality. In addition, there have been advances in OTN technologies and protocols that have made available a new generation of equipment that features a high degree of functional integration and is capable of supporting an embedded intelligent control plane (CP). This panel will examine the industry trends and deployment of emerging optical services in carrier network.
Thursday, March 26, 1:00 p.m.–3:00 p.m.
NFOEC 2: Network Technologies
NThD, 40G Deployment in Carrier Networks, Alan Gibbemeyer; Nokia Siemens Networks, USA.
40G deployments are growing rapidly driven initially by router interconnectivity with very strong growth projections for the future across the market analyst community. Some analysts are expecting 40G ports to outnumber 10G during this calendar year and bandwidth growth is continuing to exceed expectations at carriers as well as large enterprises. Systems utilizing 10G technology are running out of capacity too quickly forcing the operators to overbuild and procure additional facilities such as fiber and space. New technologies like 100G will still need time to mature meaning that 40G technology will enjoy significant growth for some time to come. We will look at the status of 40G in the carrier DWDM networks, drivers for going to 40G as well as the challenges in rolling out this new generation technology. We will also investigate alternatives to 40G and offer an expert opinion on what to watch for in the near future.
