- Abstract
A hollow-waveguide-output uni-travelling-carrier photodiode (UTC-PD) module operating at frequencies from 400 to 900 GHz has been developed. The module consists of a UTC-PD, a photodiode-to-waveguide coupler, and a metallic package with a waveguide rectangular (WR)-1.5 rectangular waveguide. The coupler is monolithically integrated with the UTC-PD chip. The fabricated module exhibits the output power as high as -19 dBm at 500 GHz and the 3 dB bandwidth of 340 GHz, which is the widest among ever-reported photodiode modules.
