摘　　要：In practical optical communication systems,there are some factors that can affect transmission quality of optical solitons.The constant coefficient nonlinear Schrödinger(NLS)equation has been unable to meet the actual research needs.We need to use the variable coefficient NLS equation to simulate an actual system,so as to explore its potential application value.Based on the variable coefficient NLS equation,six dispersion decreasing fibers(DDFs)with different dispersion curve functions are used as transmission media to study generation and interaction of two solitons in an optical communication system.The two soliton interaction phenomena,such as the bound state solitons,are theoretically obtained.Moreover,the output characteristics of bound state solitons in different DDFs are discussed,which enriches the transmission phenomenon of two solitons in the optical communication system.This study has great application value in fields such as optical information processing devices,condensed matter physics,and plasma,and provides an indispensable theoretical basis for development of new optical devices.
