Abstract
We propose and experimentally demonstrate the feasibility high refractive indices measurement (larger than the fiber cladding index) by using individual radiation mode resonances of tilted fiber Bragg gratings. By tracking a single cladding mode relative to the Bragg resonance, improved sensitivity for refractive index measurement has been achieved and the temperature fluctuations could be eliminated. The maximum index sensitivity is 5×10-4 with a detected power resolution of 0.1dB.
