Beyond Telecom and Datacom: Optical Interconnects for the Computercom Era
Organizers:
Clint Schow, IBM T. J. Watson Res. Ctr., USA
Michael Tan, Hewlett Packard Labs, USA
Performance gains in computer systems are increasingly achieved through interconnecting large numbers of parallel processor nodes. The resulting demands on communication bandwidth are extremely challenging, with the computer backplane or the telecom terminal backplane looming as one of the primary bottlenecks to information transfer. Within the next decade, Exaflop-scale machines will be produced that incorporate well over 1 million optical interconnects. Traditional Datacom transceiver technology is too costly, bulky, and power hungry to support this scale of deployment. A new class of optimized short-reach, low-power and low-cost optical interconnects must therefore be developed to enable next-generation large-scale systems. This symposium will frame the Computercom interconnect challenge from several viewpoints. Speakers from system companies will detail the requirements of optical links for future systems. The capabilities of today’s optical modules and prospects for scaling current devices and packaging into the future will be provided by speakers from Datacom transceiver companies. Finally, speakers from the research community will discuss the potential of emerging technologies that have not yet been fully developed or commercialized, but that offer the promise of enabling massive amounts of short-reach interconnect bandwidth at low-cost, with low-power consumption, a high area density, and potential for future scalability.

Symposium on Quantum Communications
Organizers:
Richard Hughes, Los Alamos Natl. Lab, USA
Thomas Chapuran, Telcordia Technologies, USA
Quantum communications using the transmission of single-photon states was invented 25 years ago. It is now an emerging technology for providing cryptographic services, especially key distribution, with security assurances rooted in laws of physics: passive monitoring of single-photon signals is not possible; and owing to the Heisenberg Uncertainty Principle active interception and retransmission introduces a disturbance, which the intended users can detect and defeat, within the assumptions of a security protocol. Because quantum communications are therefore not susceptible to an archival attack, they offer a potentially appealing alternative to public key-based methods of cryptographic key distribution, which are already retroactively vulnerable to future algorithmic attacks. Since the first experiments in 1991, quantum communications in optical fiber have seen remarkable progress in range, domains of use, and understanding of transmission impairments in a network environment. Large-scale demonstrations of quantum communications have taken place in the past year in several countries, and commercial standards activities are underway. The symposium will provide an overview of quantum communications in optical fiber networks, with presentations from the leading research groups around the world.
Tuesday, March 23, 2:00 p.m.–4:00 p.m.
