光纤中皮秒级光孤子的传输研究

Optical transmission speed and capacity are mainly determined by the pulse width caused by the group velocity dispersion of fiber. But the limitations and disadvantages which use the wavelength of zero group velocity dispersion to have ultra-high-speed, long distance communication has begun to appear.The optical soliton technology is one of the means to solve this problem.On the premise of ignoring the fiber loss in this paper,the transmission characteristics of picosecond optical soliton of First-order,Second-order and Third-order in optical fiber and the interactions between the second and third order picosecond optical solitons are studied with the step Fourier method.The simulation analysis are also given in this paper.
