Zero-dispersion wavelength and mode field diameter managements of ZDSF by optimization technique

Abstract

A proposal for the new graded index single mode optical fiber applicable in zero-dispersion communication is presented in this paper. This method is capable to set the zero-dispersion wavelength and mode field diameter in the predefined desired values. The systematic design of the mode field diameter is suggested in this paper for the first time. The dispersion management is done by optimizing the structural parameters of the cladding layers with the aid of fitness function in the Genetic algorithm technique. The special assumption for the electrical field distribution of the core region is responsible to mode field diameter adjustment.
