Abstract
The numerical and experimental analysis on the use of thinned fiber Bragg gratings as refractive index sensors have been carried out. Wet chemical etching in a buffered hydrofluoric acid (HF) solution was used for sensor fabrication. Experimental characterization for an 8.5/spl mu/m etched cladding sensor is presented demonstrating resolutions of /spl ap/10/sup -5/ and /spl ap/10/sup -4/ for outer refractive index around 1.45 and 1.333, respectively.
