Design, Simulation, Fabrication and Characterization of Optical Metasurface

Abstract

Optical metasurface is an emerging concept in the field of nano optics, nano photonics, and silicon photonics. It is an idea of creating novel planar optical devices based on space discretization and phase reconstruction method. The targeting wavelength of optical metasurface ranges from ultraviolet to near infrared bandwidths based on its application. It is a groundbreaking approach with which people for the first time can have full control of wavefront. The control is achieved through the alteration of phase, transmission and polarization at a single plane simultaneously. This dissertation is a summary of the author’s research in the field of optical metasurface including a complete process of design, simulation, fabrication and characterization of optical metasurface. The major contribution of his study lies in visible band metalens, which is of great interest in the field of imaging and sensing.
