Parameters definition task of an optimum optical pulse propagation in a line with interference properties

Abstract

The necessity of influence multibeam interference is shown on the form of chirped pulse, extending on fiber-optic line or network active components. For successful realization of symbolical coding in similar networks an invariance of transmitted information parameter consisting in the form of bending around capacity of pulse. The mathematical modeling of the optical pulse form changes in case of action multibeam interference, dispersion, nonlinear change of a refraction parameter and attenuation was carried out for revealing required bending around and chirp. Search of the pulse form was carried out on a minimum deviation of the initial form from for particular example. It is established, that the essential factors of distortions are multibeam interference especially with action of the maximum orders and dispersion; nonlinear refraction and attenuation are displayed more poorly. In a number of cases the distortion connected with first interferention order, can be compensate by selection of bending around capacity.
