We present a high-performance photoconductive terahertz detector based on plasmonic terahertz nano-antenna arrays. We demonstrate terahertz detection with record-high signal-to-noise ratio levels as high as 107 dB over a 5 THz detection bandwidth.
We present a highly efficient photoconductive terahertz generation scheme based on photon trapping. We utilize this scheme to demonstrate record-high pulsed terahertz radiation powers as high as 4 mW over 0.1–5 THz frequency.
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 demonstrate that large-area plasmonic photoconductive sources fabricated on ErAs:InGaAs can offer record-high pulsed terahertz radiation power levels as high as 300 μW over 0.1–5 THz frequency range at telecommunication optical pump wavelengths.
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 demonstrate that incorporating plasmonic nanoantennas in large-area photoconductive sources enables record-high terahertz radiation powers as high as 3.8 mW over 0.1–5 THz and an order-of-magnitude higher optical-to-terahertz conversion efficiencies compared to conventional designs.
In this paper, we present a novel design of large-area photoconductive emitters which incorporates plasmonic contact electrodes to offer significantly higher optical-to-terahertz conversion efficiencies compared with conventional designs. Use of plasmonic contact electrodes enables a more efficient separation and acceleration of photocarriers, enhancing the effective dipole moment induced within the...
