In this paper reflectivity spectra of fiber Bragg grating structure for different appodization techniques are computed and plotted as a function of operating wavelength with 1.55nm central value. Computation is made using coupled mode approach and variation of index change is considered as the turning parameter along with grating length. Result is compared with that obtained in absence of appodization thus variation of bandwidth due to deformation in wave shape is investigated. Simulated results are critically important for calculating reflectivity for practical application.
