▎ 摘  要

We investigate theoretically the photonic spin Hall effect (SHE) in a layered nanostructure containing graphene. When a propagating wave exists in a nanostructure containing graphene, it is found that near the transmission resonance of the nanostructure, the giant photonic SHE of the reflected beam is present. When an evanescent wave exists in a nanostructure containing graphene, we show that the photonic SHE of the reflected and transmitted beams can both be enhanced near the tunneling resonance. Through manipulating the voltage applied to graphene via an exterior gate, the corresponding large transverse displacement of the light beam from the photonic SHE near resonance can be easily regulated. By combing with the weak measurement method, it is expected that these phenomena may lead to some potential application for developing new nanophotonic devices. (C) 2018 Optical Society of America
