Abstract
An InGaAs/InP rib-loaded waveguide PIN photodetector integrated with a microwave coplanar waveguide transmission line on a semi-insulating InP substrate is demonstrated. The detector has a 3 dB frequency response in excess of 20 GHs. The DC responsivity of the waveguide photodetector remains constant at 0.21 A/W over a range of incident optical powers from 400 mu W to 20 mW.
