Novel Optical fiber sensor based on Tamm plasma resonance

Tamm plasma resonance(TPR) has high sensitivity and narrow full width at half maximum (FWHW), which makes it a novel type of plasmon. Considering good portability of optical fiber sensor, an optical fiber sensor based on Tamm plasma resonance is proposed, where the TPR is generated by distributed Bragg reflector and ridge-shaped Ag film. Furthermore, distributed Bragg reflector composites SiO2 and TiO2, and Refractive index sensitivity of introduced sensor is 167.02nm/RIU, quality factor is 34. This work opens up new ideas for Tamm plasma resonance sensors.
