ItemElectrical tuning of reflectance of graphene metasurface for unpolarized long wavelength infrared lightShrestha, VR ; Gao, Y ; Amani, M ; Bullock, J ; Javey, A ; Crozier, KB (OSA, 2018-01-01)We demonstrate a graphene-metal metasurface for unpolarized long wavelength infrared light with electrically-tunable reflectance. By applying a gate voltage, we shift the wavelength of a resonant reflectance dip centered at ~9.4 micron by~156 nm.

ItemMid-infrared Magnetic Mirror Based on a Hybrid Metal/Dielectric MetasurfaceYe, M ; Li, S ; Gao, Y ; Shrestha, VR ; Crozier, KB (IEEE, 2018)We propose a hybrid metal/dielectric metasurface that functions as a mid-infrared magnetic mirror. It consists amorphous silicon cuboids on gold. The physical mechanism is explained by image theory. Measured reflection spectra agree with simulations.
