Abstract :
We present the impact of changes in core refraction modulation profile and index on the shape of fibre Bragg grating reflection coefficient. It is shown that there exists a shift of reflection coefficient characteristics towards longer wavelengths and an increase in amplitude and the grating effective length as well. Reflection coefficient shapes are plotted for the profile described by hyperbolic tangent function for the selected positive values of a parameter
