Polarization Switchable Enhanced Photonic Spin Hall Effect for Optical Switch and Filters

In this letter, by merging the wave-guiding and surface plasmonic resonance (SPR) effect, a novel method has been proposed to get the enhanced and polarization-switchable photonic spin Hall effect (PSHE). This novelty has been gained by using a dielectric (glass) wave-guiding layer along with a standard Kretschmann configuration. Outcomes offer the opportunity of eliminating any physical alteration of the given structure to govern the desired results. This research is highly suited to controlling the active polarization mode of enhanced PSHE by only altering the incident resonance angle. It will be a simple alternative for modern light polarization (spin) based devices such as switches, beam splitters, filters, etc.
