Guest Editor Yuantao Teng (Jilin Normal University, Shiping City, China)
Dispersion can lead to broadening in the process of optical pulse transmission, which results in intersymbol interference that limits the development of fiber with high speed and large capacity. Conducting efficient compensation to the dispersion in an optical fiber communication system has become a significant research topic. This study adopts vector effective index method to conduct numerical simulation and analysis on the characteristics and nonlinear effects of photonic crystal fiber dispersion. The characteristics and nonlinear effects of photonic crystal fiber dispersion are analyzed by changing the structural parameters of photonic crystal fiber, such as the diameter of an air hole and the space between air holes. The numerical simulation shows that the dispersion coefficient, dispersion slope, and nonlinear coefficient of photonic crystal fiber dispersion change with structural parameters; therefore, broadband dispersion compensation can be achieved by changing the structural parameters. To achieve low-linearity and high-efficiency dispersion compensation of the conventional single-mode fiber, we have to optimize the structure of photonic crystal fibers. The results of this study have guiding significance for the structural design of photonic crystal fiber dispersion compensation.
