利用传输矩阵研究了银-光子晶体-银结构中两Tamm等离子体极化激元(TPPs)的耦合态。我们的数值结果表明当光子晶体的周期数n>10时,存在两本征波长相同的非耦合Tamm等离子体极化激元(非耦合TPPs),当n≤10时,两非耦合Tamm等离子体极化激元发生耦合,劈裂成两本征波长不同的耦合Tamm等离子体极化激元。随着n的减小,两耦合Tamm等离子体极化激元(耦合TPPs)间的劈裂能量增大,当n=3时,劈裂能量达到287.5meV。从银-光子晶体-银结构中的实时电场分布可以得到:本征波长较长的耦合TPP由两非耦合TPPs对称耦合产生,而本征波长较短的耦合TPP由两非耦合TPPs反对称耦合产生。 The coupling states of two Tamm plasmon polaritons (TPPs) in a silver-photonic crystal-silver structure were studied by using transfer matrix. Our numerical results show that there are two uncoupled Tamm plasmon polaritons (uncoupled TPPs) with the same intrinsic wavelength when the number of photon crystal cycles n> 10. When n≤10, two uncoupled Tamm plasmas Polarimetric coupling occurs and splits into two coupled Tamm plasmon polaritons with different intrinsic wavelengths. With the decrease of n, the splitting energy increases between the two coupled Tamm plasmon polaritons (coupled TPPs). When n = 3, the splitting energy reaches 287.5meV. From the real-time electric field distribution in the silver-photonic crystal-silver structure, we can get that the coupling TPP with longer eigen-wavelength is generated by the symmetric coupling of two uncoupled TPPs and the coupling TPP with shorter eigen-wavelength is composed of two uncoupled TPPs produce.
