Abstract

Reconfigurable or tunable metasurfaces are of great interest for adaptive multi-modal sensing and imaging. Phase change materials (PCMs) have been recently explored for reconfigurable optical devices such as spatial light modulators and metasurfaces. In this talk, we will present large-scale reconfigurable infrared metasurfaces consisting of greater than 30 million pixelated optical antennas integrated with PCM mesa structures over a 1cm x 1cm area.
