Abstract
Recently, metasurfaces are integrated with existing devices such as LEDs and lasers, further extending their applications more. Here, we have attempted to miniaturize existing bulky optical components by combining metasurfaces with a surface-emitting photonic bandedge laser. We designed a photonic bandedge laser that generates linearly polarized light by changing circles as ellipses in photonic crystals. By combining metasurface-based quarter-wave plates, axicon lenses, and vortex lenses on the photonic crystals, we confirmed the effective generation of circularly polarized light that simultaneously forms Bessel beams and vortex beams. Our proposed structure is expected to be used in various fields where circularly polarized light is used, such as 3D displays, optical communications, and light detection and ranging (LiDAR)s etc.
