A family of ultrafast photodetectors based on evanescently coupled photodiodes, is described. The waveguide-integrated detectors are monolithically integrated with bias-Ts, coplanar transmission lines and MMI-couplers, employing semi-insulating optical waveguides on a semi-insulating InP:Fe substrate. The integration scheme is explained and demonstrated by examples of miniaturized ultra-broadband-, traveling wave-, and narrowband photodetectors, operating up to frequencies exceeding 120 GHz.
