Electro-optically tunable active metasurfaces

Electro-optically tunable active metasurfaces that enable dynamic modulation of reflection and transmission amplitude, phase, and polarization using resonantly excited materials and phenomena are powerful design elements for meta-imaging and computation. As flat, low-profile optical elements, active metasurfaces have potential serve as cascadable, programmable components in optical meta-imaging systems, such as lens-less cameras and single-photon imaging systems. In this talk, I will discuss active metasurface designs with high quality factor, local, resonant elements, tunable via electrooptic and thermo-optic control.
