TI  - IMPLEMENTATION OF LONG-PERIOD FIBER GRATINGS FOR REFRACTIVE INDEX MEASUREMENT OF LIQUIDS
AB  - Refractive index (RI) is one of the optical parameters that is of paramount interest in characterizing liquid solutions and solvents.Increased public awareness and legal requirements for quality standards in different sectors have created a need forreliable, fast, automated, remote and/or portable refractive index sensors with multi-measurement capability. The fiber-basedRI sensors are very good candidates in providing attractive solutions in such application areas and have been attracting agrowing interest by the scientific community. In this work, a fiber optic refractive index sensor has been investigated. It uses along-period fiber grating (LPFG) and an Optical Spectrum Analyzer (OSA), as sensor head and interrogator unit, respectively.New measurements of refractive indices of common solvents and solutions at the low-loss telecom wavelength band have beensuccessfully demonstrated by using the proposed sensor. The reported measurement results are in excellent agreement with oursimulation results and reference measurements realized by conventional measurement techniques.
