【 摘 要 】

Unidirectional light propagation is achieved by use of magnetoplasmonic structure comprising magneto-optical material and photonic crystal. The physical mechanism of unidirectional propagation is analysed. Graphene layers are inserted into the dielectric layers of photonic crystal. The effect of graphene chemical potential on transmission is investigated. Active control of unidirectional propagation is realized due to the introduction of graphene layers. The dependence of transmission on incident angle is also investigated.
