Abstract

Abstract:

We demonstrate fabrication of tilted fiber Bragg gratings (TFBGs) with different tilt angles for the measurement of surrounding refractive index (SRI). High order
cladding modes has been found to disappear gradually, with their resonance wavelength linearly increasing as SRI increases. The measured index sensitivity is higher than 500 nm/RIU. By optimizing the tilt angle of the grating, the proposed optical fiber sensor can be used for SRI measurements in different index range.

Key words: optical fiber sensor, surrounding refractive index (SRI), tilted fiber Bragg gratings(TFBGs)
