Rabi-like splitting and refractive index sensing with hybrid Tamm plasmon-cavity modes

Abstract Rabi-like splitting and self-referenced refractive index sensing in hybrid plasmonic-1D photonic crystal structures have been theoretically demonstrated. The coupling between Tamm plasmon cavity photon modes are tuned by incorporating a low spacer layer adjacent to the metallic form their modes. Anticrossing of observed at different values thickness validates strong two causes with energy. has supported coupled mode theory. energy decreases increasing number periods ( N ) contrast ? dielectric materials used make 1D crystals, variation is explained an analytical model. Angular polarization dependency shows that lower much stronger than upper mode. On further investigation, it seen one remains unchanged while other undergoes significant change varying medium. This nature utilized for designing sensors analytes.
