Abstract
Bragg wavelength shift is numerically studied for different apodization profiles of chirped fiber Bragg grating (FBG). Linear
and nonlinear cases are modeled and investigated. The values of the electric field and refractive index have been
calculated using the numerical integration of the nonlinear coupled mode equation through Runge-Kutta method. Effects of
temperature, pressure and strain under the sea level are studied together with the effect of nonlinearity. Finally, a zero shift
has been obtained for each profile for enhancing the performance of FBGs.
