本文提出了一种利用高折射率-对比度光学Tamm等离子体（OTP）结构的折射率传感新概念，即涂覆金属的空气/介质交替层分布布拉格反射器（DBR）。在构造反射光谱中，出现了与OTP形成有关的倾角。该倾角的波长和反射率对环境折射率变化敏感，为实现大测量范围、高灵敏度的折射率传感提供了一种潜在的途径。(C) 2014年美国光学学会
This paper proposes a novel concept of refractive index sensing taking advantage of a high-refractive-index-contrast optical Tamm plasmon (OTP) structure, i.e., an air/dielectric alternate-layered distributed Bragg reflector (DBR) coated with metal. In the reflection spectrum of the structure, a dip related to the formation of OTP appears. The wavelength and reflectivity of this dip are sensitive to variation of ambient refractive index, which provides a potential way to realize refractive index sensing with a large measuring range and high sensitivity.
