Abstract
A hybrid plasmonic-pyroelectric detector and laser detection system is disclosed. The hybrid plasmonic-pyroelectric detector includes a substrate and a refractory ground plane mounted on a surface of the substrate. A plasmonic array defines a plurality of apertures formed in the array. A highly-oriented pyroelectric layer is mounted on a surface of the ground plane and a surface of the plasmonic array. The plasmonic array is constructed and arranged to select particular wavelengths. Alternatively, a semiconductor or an avalanche material may be used. A pair of electrode contacts are coupled to each of the plasmonic array and the refractory ground plane. A laser detection system in accordance with the disclosure includes a mechanical chopper, a lens, a folding mirror, and a chip carrier for mounting the hybrid plasmonic-pyroelectric detector.
