Paper Abstract

During the past decades, breakthroughs in nanophotonics and nanofabrication technologies have vigorously promoted the development of optical metastructures. With the help of precise design on metastructures, incident light can be effectively manipulated. However, the difficulty in finding high-index and low-loss dielectrics in visible range limits the application of all-dielectric metastructures for visible wavelengths. Besides, the edge and surface roughness of fabricated metastructure also have more significant effects on its performance. Here, we report the design of high contrast all-dielectric metastructure for visible range applications using the switchable all-dielectric metastructure an example. The physics behind the high contrast all dielectric metastructure is studied and analyzed. Based on this, the effect of edge and surface roughness on fabricated high contrast all-dielectric metastructure is explained. A method that can optimize the metastructure performance effectively is also proposed.
