    Visible to Long-Wave Infrared Photodetectors based on Copper Tetracyanoquinodimethane (CuTCNQ) Crystals
    Balendhran, S ; Hussain, Z ; Shrestha, VR ; Cadusch, J ; Ye, M ; Kim, H ; Ramanathan, R ; Bullock, J ; Javey, A ; Bansal, V ; Crozier, KB (OSA - Optical Society of America, 2020-08-01)
    We demonstrate room-temperature photodetectors at wavelengths from visible (450 nm, 532 nm) to near- (850 nm), short-wave (1550 nm), mid-wave (4.5 \mu m) and long-wave (8.35 \mu m) infrared. These are based on drop-cast Cu TCNQ crystals.

    Material identification by plasmonic infrared microspectrometer employing machine learning
    Meng, J ; Weston, L ; Balendhran, S ; Wen, D ; Cadusch, JJ ; Unnithan, RR ; Crozier, KB (Optica Publishing Group, 2021-01-01)
    We demonstrate a microspectrometer comprising plasmonic filters integrated with an infrared camera. Blackbody light illuminates the material being studied, with transmitted light collected by the microspectrometer. The latter uses machine learning to identify the material.
