    Summary

    This study introduces a novel refractive index sensor utilizing a high-refractive-index-contrast optical Tamm plasmon (OTP) structure. The sensor demonstrates high sensitivity and a large measuring range for refractive index variations.

    Area of Science:

    • Photonics and Plasmonics
    • Optical Sensing
    • Materials Science

    Background:

    • Optical Tamm plasmons (OTPs) are surface electromagnetic waves formed at the interface of a metal and a periodic dielectric structure.
    • High-refractive-index-contrast structures offer enhanced light confinement and sensitivity in photonic devices.
    • Distributed Bragg reflectors (DBRs) are widely used in optics for their precise wavelength selectivity.

    Purpose of the Study:

    • To propose and investigate a novel refractive index sensing concept based on optical Tamm plasmons.
    • To explore the potential of a high-refractive-index-contrast OTP structure for sensitive refractive index measurements.
