A monolithically integrated, lumped 4OGbit/s photoreceiver consisting of an InGaAs pin-photodetector, an InP/InGaAs SHBT transimpedance and a differential post-amplifier is presented. The complete circuit has an optical/electrical bandwidth of 28GHz. The open 40 Gbit/s eye diagrams demonstrate the successful highspeed operation of the photoreceiver. The transimpedance gain of the circuit was measured to be 3.3 k ohm (differential) which is the highest transimpedance yet reported for any.monolithically integrated 40 Gbit/s photoreceiver.
