Abstract: A metasurface includes a plurality of Bragg mirrors, each having a defect cavity therein, arrayed in a grid. A heat source is provided for each of the plurality of Bragg mirrors. Each heat source is positioned to selectively modulate heat applied to its respective Bragg mirror and to impart a different phase shift via the applied heat from the heat source.
