High speed photoreceiver over 100 GHz and its application

In this report, we present 100 GHz fiber-fed optical-to-radio converter using all optical resource, without external electric power supply. The radio and power simultaneous generation technology from a zero-bias operational uni-travelling carrier (UTC) high speed photodetector will be discussed. To improve the optical-to-electrical conversion efficiency, the hybrid integrated circuit with 110 GHz InP-PHEMT amplifier driven by electric power supply from UTC-PD was demonstrated.
