Abstract
Dielectric and semiconductor meta-surfaces offer the potential to construct high-efficiency, compact optical components through nanoscale patterning. There currently is substantial interest in developing dynamically reconfigurable and switchable meta-structures, such that the behavior can be tuned in real-time. In this work, we experimentally demonstrate electrically and thermally tunable meta-structures that utilize metal-insulator phase transitions. We demonstrate 1) switching between dielectric and plasmonic resonances in VO2 Mie resonators and 2) electrically-controlled, continuous, broadband tuning of infrared reflection and absorption in hybrid Ge-VO2 structures.
