Abstract

Energy Engineering and Power Technology Electrical and Electronic Engineering
We present a high-efficiency photoconductive terahertz source based on three-dimensional plasmonic contact electrodes. We experimentally demonstrate 105 μW broadband terahertz radiation in 0.1-2 THz frequency range in response to a 1.4 mW optical pump, exhibiting a record-high optical-to-terahertz conversion efficiency of 7.5%
