20 Gbit/s monolithic photoreceiver consisting ofa waveguide pin photodiode and HEMT distributed amplifier

Abstract
A monolithic photoreceiver OEIC for λ = 1.55 µm consisting of a waveguide pin photodiode and an InAlAs/InGaAs HEMT distributed amplifier has been fabricated using a single-step MOVPE growth technique. It has a 3 dB-down frequency of 20 GHz and operates at 20 Gbit/s with a sensitivity of –10.4 dBm.
