"High-density free-space optical interconnection fabrics"

Presentation at McGill University, September 15, 1997
We briefly review free-space optical interconnections based on
micro-beam optics. The interconnections are suitable to construct future
large-scale interconnection systems because their simple structure and
low coupling loss. Two prototypes, a digital free-space optical
switching module using micro-beam optical interconnections using stacked
planar optics and exciton absorption reflection switch (EARS) arrays and
board-to-board free-space optical interconnections having relay-lens
optics and active alignment systems, are demonstrated.
Tsuyoshi Yamamoto was born in Osaka, Japan, on November 9, 1968. He
received B. E. degree in Electrical Engineering from Kansai University,
Osaka, Japan, in 1991. Since he joined NTT Communication Switching
Laboratories, in 1991, he has been engaged in research and development
on digital free-space photonic switching systems using micro-beam
optical interconnections and exciton absorption reflection switch (EARS)
arrays. He is presently Research Engineer of NTT Network Service Systems
Laboratories. Mr. Yamamoto is a member of the Institute of Electronics,
Information and Communication Engineers of Japan (IEICE), the Japan
Society of Applied Physics, the Optical Society of Japan, and the
