Optical metasurfaces

Abstract

During the past decade we observed the rapid development of the field of optical metasurfaces, two-dimensional planar structures composed of optical resonators of different shapes and types. Metasurfaces have become a highly demanding field of research due to their exceptional abilities to manipulate light and versatility in applications of ultrathin optical devices. Metasurfaces have been suggested for a complete control of light−matter interaction with subwavelength structures, and they have been explored widely for various applications such as bending of light, metalenses, metaholograms, and nonlinear optics. Here we provide a general insight into the field and discuss some functionalities of metasurfaces highlighting their biomedical, computational, and quantum applications. Show more
