High-power continuous-terahertz-wave generation using resonant-antenna-integrated uni-travellingcarrier photodiode

The fabrication of uni-travelling-carrier photodiodes with a resonant antenna for generating high-power continuous terahertz waves is reported. Enhancement of the output power is achieved at frequencies from 0.7 to 1.6 THz, and the maximum output power obtained at 1.04 THz is 10.9 (mu)W.
