Optical Information Science
Abstract
The purpose of this in-house program was to develop techniques, architectures and systems in optical information science to support AF programs in advanced computer concepts and signal processing. We concentrated on bringing optical interconnects into advanced architectures as a way of reducing latency in interprocessor communications, especially at the memory level. We began by exploring free space interconnection and designed a selective receiver to allow high signal-to-noise interconnects with low power emitters on processors. In parallel, we researched ways of optically interconnecting a fielded computational cluster where the processors were PS3 commodity computers that use the Cell Broadband Engine (CBE). Later we helped the Wireless Computational Network Architecture (WCNA) program with optical interconnects to act as backup systems in the case of RF jamming, act as very short range interconnects where RF intermodulation distortion did not allow use of wireless and as a way of connecting wireless computational cluster nodes separated by long distances.
