Description
Summary:Metasurface optics devices feature powerful capability for wavefront manipulation by guiding the propagation of incident light efficiently. We present a classification of freestanding dielectric meta-optics to achieve efficient ultrathin optical elements and guiding light without metals. Specifically, freestanding dielectric metasurfaces provide advanced features solely described by structural design and improve coupling efficiency by removing the substrate. A few freestanding meta-devices operating at near-infrared (near-IR) wavelength (1.55 µm) have been designed and verified numerically.
