Abstract:
We present a molecular-beam-epitaxy-grown In1−xAlxAs/InAs/AlyGa1−ySb heterostructure platform that enables electrically induced free-carrier tuning of high-index Mie-resonant antennas. Forward-biased p-i-n resonators exhibit >200 nm blueshift of the fundamental resonance, paving the way to solid-state, electrically reconfigurable metasurface phased arrays.
