Abstract

The spectral response of uniform long period fiber grating is analyzed theoretically considering fluoride contaminated water as its surrounding medium. The response is studied for fluoride concentration variations ranging from 1 to 20 ppm. Our analysis is based on the study of shift in resonance wavelength of the grating with change in effective refractive indices of cladding modes due to change in fluoride ion concentration in water. Results provide insight on the use of long period fiber grating for investigation of fluoride concentration in water. Keywords: Long-period fiber grating, refractive index, fluoride concentrations, two-layer fiber geometryCite this ArticleJain V, Kumbhaj S, Sen PK.
