    Mid-infrared computational spectroscopy with an electrically-tunable graphene metasurface
    Shrestha, VR ; Craig, B ; Amani, M ; Bullock, J ; Javey, A ; Crozier, KB (OSA - Optical Society of America, 2019-01-01)
    We demonstrate graphene-plasmonic metasurfaces whose mid-infrared reflection spectra are electrically-tunable. Using measurements of the power reflected by the metasurfaces at different drive voltages, the source spectrum is computationally reconstructed by the recursive least squares method.
