Tunable beam-steering using all-dielectric metasurface for polarization independent MIR applications (Conference Presentation)

Abstract

Using all-dielectric metasurfaces has be the interest of the scientific community recently. This is because the conventionally used plasmonic resonator-based metasurfaces have high ohmic losses in the optical domain. On the other hand, dielectric materials have minimal losses in the optical regime. Dielectric metasurfaces are based on dielectric resonators, periodic sub-wavelength structures that exhibit electric and magnetic resonance near the operation wavelength. In this work a novel all-dielectric metasurface design is studied using Electro-optic polymers. Applying an electric potential over the electro-optic polymer can change the steering angle of the metasurface. This study is done using finite difference time domain simulation for the optical behavior of this structure. This structure is CMOS compatible contrary to plasmonic metasurfaces.
