Ultrabroadband Detection of Terahertz Radiation up to 20 THz with an LT-GaAs Photoconductive Antenna Gated by a 15-fs Laser Pulses

Abstract

We report on the ultrabroadband detection of terahertz radiation with a low-temperature grown GaAs photoconductive dipole antenna gated with 15-fs laser pulses. The detected spectral frequency exceeds 20 THz. This is the highest frequency detected with a photoconductive antenna reported so far.
