Spin-Hall effect of light, thin films, surface plasmons, resonance energy transfer, spin-orbit coupling
- We present a new way to obtain large spin Hall effect of light (SHEL) in nonparaxial situations. We use near field of
dipoles which contain all plane waves, both homogeneous and evanescent. We base SHEL on dipole–dipole interaction
initiated energy transfer (FRET), which we further enhance using plasmonic platforms. The spin–orbit coupling
inherent in Maxwell equations is seen in the conversion of a σ+ photon to a σ- photon. The FRET is mediated
by the resonant surface plasmons (SPs), and hence we find very large SHEL. We present explicit results for SHEL on
metal films. We also study how the splitting of the SP on a metal film affects the SHEL.
