We present a novel photoconductive terahertz source that can generate high power and broadband terahertz radiation with high optical-to-terahertz conversion efficiency. The high optical-to-terahertz conversion efficiency is achieved by confining the optical pump photons very tightly around the radiating elements of the photoconductive source. A distributed Bragg reflector and plasmonic nanostructures...
We present a novel large-area photoconductive terahertz emitter based on a 2D plasmonic nano-antenna array and compatible with telecommunication optical wavelengths. We experimentally demonstrate a record-high terahertz radiation power level of 300μW over 0.1–5 THz frequency range.
We present a novel photoconductive terahertz detector based on a 2D plasmonic nano-antenna array. We experimentally demonstrate that this terahertz detector offers high responsivity with high signal-to-noise ratio over bandwidths exceeding 5 THz. Such a high-performance detector can be very important for the next generation compact terahertz timedomain spectroscopy systems.
We present a novel large area plasmonic photoconductive emitter and demonstrate pulsed terahertz generation with record-high radiation powers as high as 3.6 mW at an optical pump power of 150 mW over 0.1–5 THz frequency range.
