Nanomechanical metamaterial light modulators

Reconfigurable photonic metamaterials provide a flexible platform for thermo-optical, electro-optical, magneto-optical and all-optical modulation of metamaterial properties. We provide an overview from fundamental physics to practical metadevices for high-contrast light modulation

Reconfigurable gradient metasurfaces with random access

Since metamaterials have enabled the design of almost arbitrary landscapes of static optical properties and functionalities, dynamic temporal and spatial control over metamaterial properties has become the next big challenge [1]. Here we demonstrate the first randomly addressable reconfigurable metamaterials, thus enabling fast and high-contrast control over optical properties simultaneously in time and space
