Abstract
We report what we believe to be the first demonstration of an all-semiconductor room-temperature terahertz time domain spectrometer. An optical Stark mode-locked vertical-external-cavity surface-emitting laser with pulses at was used to illuminate low-temperature-grown photoconductive antennae with -gap bow-tie-shaped electrodes. The coherently detected spectrum has a bandwidth close to , in which water absorption lines at 0.555 and can be resolved.
