Spatially Controlled Optical Vortex Generation Using Low‐Loss Antimony Telluride Metasurfaces

Spatially Controlled Optical Vortex Generation Using Low‐Loss Antimony Telluride Metasurfaces

Optical vortex beams, endowed with orbital angular momentum (OAM) due to their helical wavefronts, are essential for advancements in optical manipulation, quantum computing, and communication technologies. Existing methods for generating vortex beams often struggle with issues such as low efficiency...
