Demonstration of a 40 Gb/s, 4 channel optical receiver array

We demonstrate a four-channel DWDM optical receiver array operating at 10 Gbps/channel with a sensitivity of -17 dBm and an aggregate data rate of 40 Gbps. The optical receiver is a hybrid integrated device consisting of a monolithic InGaAs p-i-n photodiode array hybridized to individual InP heterojunction bipolar transistor based transimpedance amplifiers.
