通过对超短光脉冲在单模光纤中传输方程的分析研究，给出了在零群速色散区传输方程的亮、暗孤波解。结果表明，超短光脉冲在光纤的零群速色散区仍能以亮、暗孤波的形式传输，且不存在孤子自频移现象。这对实现超短光脉冲在光纤中的长距离稳定传输和超高码率的光孤子通信系统具有重大的意义。
By analyzing the transmission equation of the ultrashort optical pulse in the single mode fiber, the bright and dark solitary wave solutions of the transmission equation in the group velocity dispersion zone are given. The results show that the ultrashort optical pulse can still be transmitted in the form of bright and dark solitary wave in the zero-group dispersion region of optical fiber, and there is no soliton self-frequency shift phenomenon. This is of great significance to realize the optical soliton communication system with long-distance stable transmission and ultra-high code rate of ultra-short optical pulses in the optical fiber.
