Free space optical interconnect using microlasers and modulator arrays.

Progress towards a free space interchip optical interconnect is described. We have fabricated an array of 36 differential optical receiver pairs in standard digital 0. 9 CMOS. The entire array occupies a square 2''lO on a side and each receiver channel can be operated up to 32OMbit/s. Link experiments are underway using these receivers in conjunction with transmitter arrays of GaAs SEEDs and microlasers. A compact opto-mechanical module for a simple system interconnect has also been designed constructed and tested.© (1991) COPYRIGHT SPIE--The International Society for Optical Engineering.
