We present a 100-GHz integrated photoreceiver using an optical-to-radio converter and an
enhancement-mode PHEMT amplifier driven by all optical resources without an external
electric power supply. Technology for the simultaneous generation of radio and power was
developed using a zero-bias operational uni-travelling carrier (UTC) high-speed
photodetector. To improve the optical-to-electrical conversion efficiency, a 110-GHz

We present a 100-GHz integrated photoreceiver using an optical-to-radio converter and an enhancement-mode PHEMT amplifier driven by all optical resources without an external electric power supply. Technology for the simultaneous generation of radio and power was developed using a zero-bias operational uni-travelling carrier (UTC) high-speed photodetector. To improve the optical-to-electrical conversion efficiency, a 110-GHz enhancement-mode InP-PHEMT amplifier was also newly developed, which operates using an internal electric power supply in an optical-to-radio converter. Using a hybrid integration based on all optical resources, a +5.5 dBm RF output at 97 GHz was successfully achieved through the optical-to-radio conversion process. Herein, the two key devices and the integrated photoreceiver are discussed.
