  • THz distributed detectors and arrays
    Patent number: 9356170
    Abstract: Terahertz (THz) distributed detectors, and arrays of detectors that utilize structured surface plasmonic effects for more efficient coupling to free space are discussed. One example distributed detector includes a detector junction comprising a Schottky or tunneling interface between a semiconductor and a detector metal, an ohmic junction comprising an ohmic interface between the semiconductor and an ohmic metal, and a gap that separates the detector junction from the ohmic junction. Structured surface plasmons concentrate an electric field in the gap when the distributed detector is exposed to THz radiation polarized perpendicular to the gap.
    Type: Grant
    Filed: March 17, 2014
    Date of Patent: May 31, 2016
    Assignee: WRIGHT STATE UNIVERSITY
    Inventors: Elliott R. Brown, John R. Middendorf, John S. Cetnar
