0.4 mW Terahertz Power Generation through Bias-Free, Telecommunication-Compatible, Photoconductive Nano-Antennas

We present a bias-free, telecommunication-compatible, photoconductive terahertz source that generates terahertz powers as high as 0.4 mW, enabling time domain terahertz spectroscopy with up to 90 dB dynamic range up to a 3.5 THz bandwidth.
