研究了非对称介质-金属-介质波纹结构中金属薄膜两面等离子激元的同时激发。由于该结构的透射侧对入射光的共振吸收很小，我们研究了通过控制结构参数对透射侧表面等离子体激元的增强。当照明光由垂直入射变为非垂直入射时，共振吸收峰分裂成一对双峰。通过控制入射角，可以实现金属薄膜两面表面等离子体激元的同时激发。由于波矢匹配条件不满足，波纹状金属薄膜的两个表面上的等离子体激元模式之间没有耦合。激发和控制非耦合表面等离子体激元在同一金属薄膜的不同界面上同时传播对于设计新型紧凑可调谐的可见光纳米光子器件具有潜在的应用价值。
The simultaneous excitation of plasmon polaritons on both surfaces of metal film was studied for asymmetric dielectric-metal-dielectric corrugated structures. Due to the small resonant absorption of the incident light on the transmission side of the structure, we investigated the enhancement of the surface plasmon polaritons on the mentioned side by controlling the structure parameters. When the illuminate light changes from normal incidence to non-normal incidence, the resonant absorption peak splits into a doublet. The simultaneous excitation of surface plasmon polaritons on both surfaces of the metal film can be achieved by controlling the incident angle. Since the wave vector matching condition is not satisfied, there is no coupling between the plasmon polaritons modes on the two surfaces of the corrugated metallic film. The excitation and control of the non-coupled surface plasmon polartions simultaneously propagating on the different interfaces of one metallic film have potential applications for designing novel compact and tunable nano-photonic devices at visible frequency.
