Field effect transistor-self electrooptic effect device (FET-SEED) differential transimpedance amplifiers for two-dimensional optical data links

A 4/spl times/18 two-dimensional array of GaAs FET-SEED (field effect transistor-self electrooptic effect device) differential transimpedence receivers has been fabricated for application in massively parallel optical data link board-to-board interconnections. Several FET-SEED receiver arrays were tested and displayed a mean response of /spl sim/0.7 mV//spl mu/W, and were capable of >100 Mbps per channel operation. The mean receiver sensitivity for a BER of >
