46 GHz bandwidth monolithic InP/InGaAs pin/SHBT photoreceiver

An InGaAs pin-photodetector and a lumped SHBT transimpedance preamplifier have been monolithically integrated and characterised. The preamlifier achieves a transimpedance gain of 44.6 dBΩ (170 Ω) and the optical/electrical –3 dB bandwidth of the entire receiver is 46 GHz, which is the highest bandwidth for any HBT based photoreceiver reported to date.
