Paper Abstract

In this paper, the impacts of surface plasmon resonance (SPR) on the angular spin splitting of light are investigated theoretically. The expression for the angular spin splitting shifts is derived, and the angular shifts as the function of the angle of incidence under different metal film thicknesses are calculated. The simulation results manifest that the angular spin splitting is significantly enhanced when surface plasmons are strongly excited. Under the optimal parameter conditions, the largest angular shift is up to 4.493×10-5 rad. It is also found that the directions of spatial propagation of photons in the out-of-plane can be switched by adjusting the angle of incidence under certain conditions. These findings may provide a new way for photon manipulation and open another possibility for the development of new nano-photonic devices.
