Waveguide-Based Chip-to-Chip Optical Interconnection Network for Distributed Computer System

A 2×2 interchip optical interconnection network is reported for distributed-memory multiprocessor system and the experiment confirmed that the data rate in each channel could reach above 3.125 Gbit per second and the bit error rate (BER) could be be up to 1.27×10
