Resonant photon tunneling was investigated experimentally in multilayer structures containing a high-contrast (TiO(2)/SiO(2)) Bragg mirror capped with a semitransparent gold film. Transmission via a fundamental cavity resonance was compared with transmission via the Tamm plasmon polariton resonance that appears at the interface between a metal film and a one-dimensional photonic bandgap structure. The Tamm-plasmon-mediated transmission exhibits a smaller dependence on the angle and polarization of the incident light for similar values of peak transmission, resonance wavelength, and finesse. Implications for transparent electrical contacts based on resonant tunneling structures are discussed.
共振光子隧穿在包含高对比度（TiO(2)/SiO(2))布拉格镜的多层结构中进行了实验研究，该布拉格镜由半透明金膜覆盖。通过基本腔共振的传输与在金属膜和一维光子带隙结构之间出现的 Tamm 等离子体激元共振的传输进行了比较。对于相似的峰值传输、共振波长和精细度值，Tamm 等离子体介导的传输对光的入射角和偏振度的依赖性较小。讨论了基于共振隧穿结构的透明电接触的应用。
