Highly Efficient Polarization Control Based on All-Dielectric Metasurfaces

Metasurfaces have been widely used in the manufacture of various optical components in recent years. Based on all-dielectric metasurfaces, we proposed broadband, high-efficiency (over 83%) quarter-wave plates (QWP) and half-wave plates (HWP), respectively. The structure of the HWP we designed is equ...

Description
Summary:Metasurfaces have been widely used in the manufacture of various optical components in recent years. Based on all-dielectric metasurfaces, we proposed broadband, high-efficiency (over 83%) quarter-wave plates (QWP) and half-wave plates (HWP), respectively. The structure of the HWP we designed is equivalent to the superposition of two QWPs. The proposed QWP and HWP have high transmission efficiency, with bandwidths of 1376-1624 nm and 1411-1584 nm, respectively. Furthermore, based on the three-layer all-dielectric metasurfaces structure, we proposed a reversible bifunctional metasurface, which can realize the function of QWP and the effect of light deflection. This work may be conducive to the miniaturization and integration of polarization conversion devices.
