Abstract
A refractive index sensor using a pressure-induced long-period grating is proposed and demonstrated. The sensing element is made of a composite optical waveguide based on a single-mode fiber. The experimental results show that the sensitivity for LP14 mode resonance is 72nm/RIU (refractive index unit) when the medium refractive index varies from 1.33 to 1.43.
