Localized high-Q resonances enable electrically defined beam steering in lithium niobate metasurfaces
Jiyong Shim, Sahil Dagli, Hamish Carr Delgado +7
High-speed beam steering for LiDAR and optical communication requires independent, reconfigurable control of optical phase. We demonstrate a metasurface combining lithium niobate's…

Factors Exceeding in Wavelength-to-Subwavelength-Scale Free-Space Resonators
Darrell E. Omo-Lamai, Varun Dolia, Yanyu Xiong +7
Free-space-addressable optical resonators that combine long photon lifetimes (high factors) with strong spatial localization of optical fields (small mode volumes, ) enhan…
