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

open access: yesAdvanced Photonics Research, EarlyView.
The spatially varying vortex beams with the customizable propagation trajectory and the controllable topological charge evolution are demonstrated using the Sb2Te3‐based plasmonic metasurfaces. Benefiting from the dispersion‐free property of the Pancharatnam–Berry phase and the broadband response of polarization conversion efficiency of the nanobrick ...

Extraction of Inherent Amplitude Mode from a Light Beam

open access: yesAdvanced Photonics Research, EarlyView.
Mode extraction is the inverse process of the double‐beam superposition principle in classical optics. While polarization mode extraction has been successfully demonstrated using an m‐order vector vortex beam, this article demonstrates the amplitude mode extraction of a light beam.
