Paper Abstract

This paper proposes a novel concept of refractive index sensing based on 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 dip wavelength and reflectivity are sensitive to ambient refractive index, which provides a potential way to achieve refractive index sensing with a large measurement range and high sensitivity.
