Abstract
An active metasurface includes a number of periodically-repeated unit cells arranged on a substrate that each include a plasmonic waveguide shaped and sized to provide a cutoff mode that captures light of a target wavelength. The active metasurface includes an index modulation controller that controllably varies a voltage differential across each one of the periodically-repeated cells to change a phase of light incident on the metasurface.
