Abstract

In this paper, we proposed and theoretically simulated the tunable all-dielectric metasurface by varying the bisecting angular gap. The Fano-resonance position for the proposed silicon-on-silica structure shows the blue-shift with an increase in the angular gap. We have also observed the steep rise in the linewidth (FWHM) due to the increase in the angular gap. Such designs of the metasurfaces can provide a customized solution for various applications like modulator, filter, biochemical sensors.
