Coupling between the optical Tamm states (OTS) and microcavity mode in one-dimensional photonic crystal (1DPhC) structures is investigated experimentally and numerically with the help of transfer matrix method in resonant and non-resonant conditions, as a function of the distance between the 1DPhC-metal interface and the cavity layer (in terms of number of bilayers, N top , between the Tamm cavity and the microcavity). The system under study comprised of twelve bi-layers of alternating SiO 2 /TiO 2 thin films, a half-wave thick TiO 2 microcavity region and a layer of silver metal on top of the structure. It is observed that the microcavity mode and the OTS repel each other when N top is reduced indicating strong coupling between the two modes. In the resonant condition, wherein the individual structure consisting of either microcavity alone or Tamm cavity alone are tuned for the configuration N top ...

一维微腔模式与光学Tamm态的共振与非共振耦合

利用共振和非共振条件下的传递矩阵法，通过一维光子晶体态（OTS）和一维光子晶体（1DPhC）结构中的微腔模式之间的耦合，通过实验研究和数值模拟，确定了耦合态之间的距离。 1DPhC-金属界面和腔层（以Tamm腔和微腔之间的双层数N top为单位）。所研究的系统由十二个交替的SiO 2 / TiO 2薄膜双层，一个半波厚的TiO 2微腔区域和在结构顶部的一层银金属组成。观察到，当N top减小时，微腔模式和OTS彼此排斥，表明两种模式之间的强耦合。在共振条件下
