%X In this paper, the simulations of the reflectance of the uniform and apodized fiber Bragg gratings (FBG) are presented. The simulations are based on the coupled¨Cmode theory. The simulated reflectances of FBGs with different lengths and the modulations of the refractive index were described. The influence on the bandwidth of the reflected spectra at the Bragg wavelength and the maxima of the reflected energy were investigated. FBGs with several types of apodized variations of the refractive indices were modeled to show how the sidelobes can be supressed.
