Abstract

The design, experimental evaluation and performance of a Traveling-Wave Uni-Traveling Carrier photodiode for Terahertz generation are described and its advantages in terms of frequency response are demonstrated. The device delivered 148 mu W at 457 GHz, 24 mu W at 914 GHz when integrated with resonant antennas and 105 mu W at 255 GHz, 30 mu W at 408 GHz, 16 mu W at 510 GHz and 10 mu W at 612 GHz. Record levels of Terahertz figure of merit (P-THz/P-opt(2) in W-1) were achieved ranging from 1 W-1 at 110 GHz to 0.0024 W-1 at 914 GHz. (C) 2010 Optical Society of America
