| Abstract: | In this paper, the background of the discover of optical soliton is introduced, the basic theory about optical soliton and the mechanism of how the optical soliton exists and the basic qualities are emphatically expressed. The evolution of optical soliton that obey the nonlinear Sehr6dinger equation and the modified nonlinear SehrSdinger equation is studied. Through the numerical simulation, some important results are obtained. Then the quasi soliton named by Hasegawa et al. is studied, the parts and principle of quasi optical soliton communication system are demonstrated, and varieties of factors that affect the transmission of optical solitons is discussed, then the corresponding methods of how to resolve or reduce these are pointed out. |
