0.25 mW Pulsed Terahertz Radiation from Bias-Free, Telecommunication-Compatible Plasmonic Nanoantennas

We present a bias-free, telecommunication-compatible photoconductive terahertz source, which offers radiation powers exceeding 0.25 mW, enabling time-domain terahertz spectroscopy with more than a 90 dB dynamic range over a 0.1-3.5 THz bandwidth. © 2019 The Author(s)
