Abstract:
A plasmonic detector is described which can resonantly enhance the performance of infrared detectors. More specifically, the disclosure is directed to enhancing the quantum efficiency of semiconductor infrared detectors by increasing coupling to the incident radiation field as a result of resonant coupling to surface plasma waves supported by the metal/semiconductor interface, without impacting the dark current of the device, resulting in an improved detectivity over the surface plasma wave spectral bandwidth.
