Abstract
We present, for the first time, the results regarding the production of refractive index (RI) sensors, through the acousto-optic effect in tilted fiber Bragg gratings (TFBGs). The RI is analysed in detail when acoustic waves are turned on using saccharose solutions with different RI from 1.3327 to 1.4249.
