Dielectric Nonlocal Metasurfaces for Fully Solid-State Ultrathin Optical Systems
Dielectric Nonlocal Metasurfaces for Fully Solid-State Ultrathin Optical Systems
Most optical systems involve a combination of lenses separated by free-space regions where light acquires the required angle-dependent phase delay for a certain functionality. Very recently, flat-optics structures have been proposed to compress these large free-space volumes and miniaturize the overall optical system. However, these early designs can only replace …
