Abstract: We report the design, fabrication and characterization of an antenna integrated, waveguide-fed, traveling-wave uni-traveling carrier photodiodes (TW-UTC-PDs). In the device, a dilute passive waveguide structure, which is easy to be coupled with a single mode fiber, is adopted. Measurement results show that broad band THz emission can be obtained for frequencies up to 700 GHz.

Keywords: Terahertz source, UTC-PD, Antenna.
