A new photodetector chip for polarization diverse detection is presented. The presented chip allows for smaller footprints and design simplifications by utilizing a waveguide-integrated multiple-quantum well photodiode (MQW-PD) serially coupled to a bulk photodiode (PD) in InP technology. The MQW-PD...
