Enhancing photonic spin Hall effect via long-range surface plasmon resonance

This is the authors' abstract. We don't add key points for this paper.

We presented the significant enhancement of the photonic spin Hall effect by taking advantage of long-range surface plasmon resonance (LRSPR). The influence of the thicknesses of metal and dielectric layers in the insulator-metal-insulator structure which supports LRSPR was investigated. Under the optimal parameter setup, the largest transverse separation with a 632.8 nm incident Gaussian beam reaches 7.85 μm, which is much larger than previous reported values.
