Abstract: A detector that includes an all-oxide, Schottky-type heterojunction. The “metal” side of the heterojunction is formed, for example, from a dysprosium (“Dy”) doped cadmium oxide (“CdO”) (i.e., CdO:Dy). The semiconductor side of the heterojunction is formed, for example, from cadmium magnesium oxide (“CdMgO”). On the metal side of the junction, “hot” electrons are created through the excitation of surface plasmon polaritons by infrared radiation. The hot electrons are able to cross the Schottky-type barrier of the heterojunction into the conduction band of the semiconductor where they can be detected. The working wavelength of infrared radiation that is being detected can be adjusted or tuned by modifying the Dy content of Dy-doped CdO. The height of the Schottky-type barrier can also be adjusted by modifying the composition of CdMgO, which allows for the optimization of the Schottky-type barrier height for a given working wavelength.

Abstract: IR emission devices comprising an array of polaritonic IR emitters arranged on a substrate, where the emitters are coupled to a heater configured to provide heat to one or more of the emitters. When the emitters are heated, they produce an infrared emission that can be polarized and whose spectral emission range, emission wavelength, and/or emission linewidth can be tuned by the polaritonic material used to form the elements of the array and/or by the size and/or shape of the emitters. The IR emission can be modulated by the induction of a strain into a ferroelectric, a change in the crystalline phase of a phase change material and/or by quickly applying and dissipating heat applied to the polaritonic nanostructure. The IR emission can be designed to be hidden in the thermal background so that it can be observed only under the appropriate filtering and/or demodulation conditions.
