Abstract

Herein, we leverage electrically driven tunable all-dielectric reflective/transmittive metasurfaces made of newly emerged classes of low-loss optical phase-change materials (PCMs), e.g., antimony trisulphide (Sb2S3) and antimony triselenide (Sb2Se3), to realize switchable, high-saturation, high-efficiency, and high-resolution dynamic meta-pixels. Exploiting polarization-sensitive building blocks, the presented meta-pixel can generate two different colors when illuminated by either one of two orthogonally polarized incident beams. Such degrees of freedom (i.e., material phase and polarization state) enable a single reconfigurable metasurface with fixed geometrical parameters to generate four distinct wide-gamut colors. We experimentally demonstrate, for the first time, an electrically driven micro-scale dual-view display through the integration of phase-change metasurfaces with an on-chip heater formed by a transparent conductive oxide.
