A uni-traveling-carrier photodiode (UTC-PD), featuring high-output power and a fast response, was monolithically integrated into a 0.1-μm-gate InP-based HEMT digital IC that can operate at over 40 Gbit/s. In the digital OEIC fabrication using our integration technology, the demultiplexing function of an optical-input D-type flip-flop (D-FF) circuit using 40-Gbit/s return-to-zero (RZ) optical signal and 20-GHz electrical clock signal was confirmed. This integration technology enables the development of a simplified receiver unit with high performance for use in 40-Gbit/s and over TDM systems
