Abstract

The optical fiber communication has been second topics only to robot study for today. In the process of the Dense Wave-Length Division Multiplexing (DWDM) study, the problem of the dispersion compensate for the traditional optical fiber is a difficult problem to be solved for long distance transport information. In order to solve this problem, it is half work and times time by experimental study on photonic crystals with high negative dispersion structure. The advanced COMSOL Multiphysics many physical fields coupling calculation software is preferred. The research methods are that the structural parameters are adjusted for the traditional hexagonal photonic crystal fiber and the negative dispersion coefficient is obtained as far as possible large. Then the structure that the several layers with same spacing is designed and the structure is with ultra-high negative dispersion coefficient. The result shows that it is several ten times of the domestic level and it is 1.1 times of the international level. It is times work and half time by COMSOL Multiphysics many physical fields coupling calculation software in Modeling, mesh subdivision, calculation and analysis. The result is the theory basis for DWDM.
