My research interests are in developing tunable nanophotonic devices. Photonics has the opportunity to revolutionize sensing and information processing applications with devices operating at the speed of light, yet optical computing technologies have not taken off due to the size limitations of conventional optical devices. Metasurfaces are a promising route to miniaturizing optical devices by using arrays of nanoscale antennas to control the phase, polarization, and amplitude of light. My work focuses on developing electrically tunable high quality factor metasurfaces using silicon and lithium niobate. Using the electro-optic Pockels effect in lithium niobate, we can electrically tune the optical response from highly resonant silicon antennas. We aim to develop a fully reconfigurable metasurface capable of shaping light as desired.
