Abstract

At the solution of a problem of synthesis of refractive index profile of optical fibres with the set dispersive characteristics by optimization methods it is important at formation of initial conditions with the maximal accuracy to come nearer to a global minimum. It demands preliminary research of dependences of chromatic dispersion slopes from parameters of refractive index profile ofan optical fibre. In the given job results of theoretical researches of chromatic dispersion slopes, its parameters (wavelength of zero dispersion, an inclination of the spectral characteristic) are submitted depending on core radius and profile height. For calculations of dispersion the known analytical expressions received on the basis of the modified Gaussian approximation method were used. Calculations have been executed for single-mode optical fibres with a step, triangular and parabolic refractive index profile in a working range of wavelengths of CWDM systems. The received results allow to predict tendencies of chromatic dispersion changes, give quantitative ratings of its spectral characteristics changes depending on the form and parameters ofrefractive index profile of an optical fibre.
