23 GHz bandwidth monolithic photoreceivercompatible with InP/InGaAs double-heterojunctionbipolar transistor fabrication process

Abstract
A 23 GHz bandwidth is achieved with a pin/DHBT photoreceiver in which the pin-PD is formed on the layer structure that corresponds to the base-to-collector region of the DHBTs. This is the widest bandwidth yet reported for monolithic photoreceivers.
