We propose the design of refractive index sensor using hybrid-modes formed due to coupling of Tamm-plasmon-polaritons (TPP) and cavity mode in Ta2O5/SiO2 based distributed Bragg-reflectors (DBR). The cavity mode sensitivity varied from 180 nm/RIU to 310 nm/RIU while the sensitivity of low frequency hybrid TPP mode varied from 70 nm/RIU to 210 nm/RIU.
