Enhanced photonic spin Hall effect with subwavelength topological edge states
Enhanced photonic spin Hall effect with subwavelength topological edge states
Abstract Photonic structures offer unique opportunities for controlling light‐matter interaction, including the photonic spin Hall effect associated with the transverse spin‐dependent displacement of a light beam that propagates in specially designed optical media. However, due to small spin‐orbit coupling, the photonic spin Hall effect is usually weak at the nanoscale. …
