Monolithic Eight-Channel Photoreceiver Array OEICs for HDWDM Applications at 1.55 μm

Eight-channel transimpedance photoreceiver array OEICs have been successfully fabricated on 2" diameter InP substrates. The yield of fully functional arrays is as high as 37%. Individual receiver channels exhibit bandwidths in excess of 300 MHz and an average input equivalent noise current of around 4.8 pA/ square root (Hz), corresponding to an inferred sensitivity of -32.1 dBm at 622 Mbit/s. Each receiver channel is designed to drive standard 50 Omega loads.
