Abstract

The uni-traveling-carrier photodiode (UTC-PD) is a novel photodiode that utilizes only electrons as the active carriers. This unique feature is the key to achieving excellent high-speed and high-output characteristics simultaneously. A record 3-dB bandwidth of 310 GHz and a millimeter-wave output power of over 20 mW at 100 GHz have already been achieved. The superior capability of the UTC-PD for generating very-large high-bit-rate electrical signals as well as a very-high output power in millimeter/sub-millimeter ranges can innovate various systems, such as broadband optical communications systems, wireless communications systems, and high-frequency measurement systems. Achievements include photoreceivers of up to 80 Gbit/s, DEMUX operations using an integrated optical gate of up to 320 Gbit/s, and a 10-Gbit/s millimeter-wave wireless link at 120 GHz. Also achieved has been high-power millimeter generation of 17 mW at 120 GHz with a waveguide-output UTC-PD module, considered for use in the photonic-local system of radio telescopes.
