Refractive index determination of HF acid using, in-situ, monitoring of etched fibre Bragg gratings
Refractive index determination of HF acid using, in-situ, monitoring of etched fibre Bragg gratings
In this work, based on simple technique of measuring the differential relative shifts of the Bragg resonances between the fundamental mode LP01 and the higher-order modes; LP11, LP02, LP21, LP12, LP31 in an etched FBG, we determine the refractive index of a buffered HF (BHF) acid solution with concentration (20:1) to be ~ 1.360± 0.005 at 1.55µm, and use that to demonstrate precise control the fibre etch diameter during the etching process. The refractive index is calibrated against known indices of liquids and solvents, including water, methanol, acetone, IPA and ethylene glycol. The experimental results were compared with simulations and exhibited excellent agreement.

Abstract
In this work, based on simple technique of measuring the differential relative shifts of the Bragg resonances between the fundamental mode LP01 and the higher-order modes; LP11, LP02, LP21, LP12, LP31 in an etched FBG, we determine the refractive index of a buffered HF (BHF) acid solution with concentration (20:1) to be ~ 1.360± 0.005 at 1.55µm, and use that to demonstrate precise control the fibre etch diameter during the etching process. The refractive index is calibrated against known indices of liquids and solvents, including water, methanol, acetone, IPA and ethylene glycol. The experimental results were compared with simulations and exhibited excellent agreement.
