Abstract

Metasurfaces provide versatile platforms for arbitrary wavefront shaping with designer optical response such as amplitude, phase, and polarization at the deep subwavelength regime. Tunable metasurfaces can bring additional degree of freedom in terms of the time-dependent change of these responses, which can pave a way for novel applications such as wide-field-of-view holographic display and light detection and ranging (LiDAR). In this talk, we present the all-dielectric metasurface array that can modulate the phase of light above 270° in reflection with high reflectivity over 60% as a function of the individually applied voltage in the near infrared regime.
