摘要：
We derive the photonic spin Hall effect (PSHE) expressions of left-handed circularly polarized (LHCP) and right-handed circularly polarized (RHCP) light from the prism-graphene waveguide structure. The effect of the magnetic field on the PSHE effect is analyzed by using the magneto optical (MO) effect of graphene at the terahertz band. The research shows that due to the existence of graphene, its optical rotation effect will greatly enhance the asymmetric splitting of LHCP and RHCP components. In addition, the incident polarized light frequency and graphene waveguide parameters, such as Fermi level and relaxation time, have very obvious influences on the PSHE shift with MO effect. Thus, the effective modulation of magnetic field to PSHE can be realized at the terahertz band, and it provides a new approach for precision measurement, new sensing and new terahertz band devices.
