Photoconductive Metasurfaces for Terahertz Detection
We developed terahertz detectors with integrated perfectly-absorbing photoconductive metasurfaces as an active region for improved efficiency and performance. The metasurface switches photoconductivity in the detector with contrast of ∼107 using substantially reduced (>10X) optical power.
