摘要
Light propagation in a coupled system of Tamm plasmon-polariton and nonlinear cavity mode is theoretically investigated through the nonlinear transfer matrix method. It is found that the asymmetric layered structure exhibits both pronounced unidirectionality and high transmission. This leads to all-optical diode actions. Compared with other similar studies, the designed structure is much simple only with seven periods. The unique feature is that the direction of on-off can be reversed depending on the working frequencies. The effect of metal loss is also considered in this study.
