Abstract

We demonstrate water-salinity sensing based on the relative shifts of the higher-order Bragg-resonances in a cladding-etched fibre Bragg grating, and achieve sensitivities of 2.9nm/RIU(LP01) and 3.4nm/RIU(LP11) atλ=1560nm for the two sets of modes

Abstract

By monitoring the wavelength-shift of Bragg-resonances in a fibre grating during cladding-etching, we measure the refractive-index of buffered-HF acid (20:1) as 1.36±0.005 @ 1.55μm, and use that to demonstrate precise control the fibre etch-diameter.
