A photoconductive infrared detector comprising a substrate, an electrode geometry, and a layer of intrinsically conductive or photoconductive donor-acceptor conjugated polymer.

Infrared detection with intrinsically conductive conjugated polymers

In accordance with various embodiments of the disclosed subject matter, a system, device and method for an electrically tunable wavelength selection filter comprising a wavelength selection filter portion having a plurality of alternating thin films of two dielectric materials with a thin film capacitor displacing one pair of alternating thin films, and an order sorting filter portion electrically isolated from but proximate the wavelength selection filter and having a plurality of alternating thin films of two dielectric materials where one of the dielectric materials exhibits a voltage-dependent refractive index. Independently controlling the capacitor charging voltage and the voltage across the order sorting filter enables selective transmission of narrow spectral lines across a desired frequency region.

An antenna array is provided including a substrate, a metal ground plane proximate the substrate, and a dielectric layer proximate the metal ground plane. A first plurality of antenna elements including polaronic organic transducer elements is proximate the dielectric layer and connected in series. A second plurality of antenna elements including polaronic organic transducer elements is proximate the dielectric layer and also connected in series. The first and second plurality of antenna elements are electrically isolated. The antenna elements of the first plurality of antenna elements are configured to detect a first wavelength, while the antenna elements of the second plurality of antenna elements are configured to detect a second wavelength, different from the first wavelength.

Integrated infrared optical antenna and polaronic organic transducer sensor

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.
