Paper Title
Effect of Grating Parameters of Fiber Bragg Grating on its Reflection Spectrum

This paper presents the effect of grating parameters on reflectivity, bandwidth and bragg wavelength of Fiber Bragg Grating. Length of the fiber, index modulation and grating period are the grating parameters. Couple mode theory is used for analysis of Fiber Bragg Grating spectrum which is solved by transfer matrix method to analyse the Spectral reflectivity with changes in the grating parameters. Simulation is carried out using Opti-grating software. Index Terms— Couple Mode Theory (CMT), Fiber Bragg Grating (FBG), Reflectivity, Transfer Matrix Method
