A High-Sensitivity Plasmonic Photoconductive Terahertz Focal-Plane Array

Not Accessible

Your library or personal account may give you access

Abstract

We demonstrate a 63-pixel photoconductive terahertz focal-plane array, which uses plasmonic nanoantennas to maximize terahertz and optical pump interaction at each pixel to provide signal-to-noise-ratios exceeding 60 dB and more than 2 THz bandwidth for all pixels.
