Abstract

Optical board-to-board interconnects for 1 - 100 cm distances are presented. A thick light- guiding plate (typically 5 - 10 mm) is used for confinement and transport of the optical signals with low loss (-0.1 dB/cm), highly efficient holographic optical elements in dichromated gelatin are used for coupling (-0.5 dB) and binary phase gratings for broadcasting of signals. Several experiments were performed: (1) point-to-point interconnects operating at a data rate of 650 Mbit/s per channel, (2) a parallel interconnect with high packing density up to 1000 channels/cm², (3) an optical permutation stage for data permutation networks, and (4) an optical star coupler for signal broadcasting within light- guiding plates. Holographic optical elements in dichromated gelatin have shown excellent diffraction efficiency and low level of straylight at wavelengths ranging from 488 nm to 1.5 micrometers .
