摘　　要：根据光脉冲在光子晶体光纤中传播的非线性薛定谔方程,分析了孤子传播基本原理,给出了光脉冲在光子晶体光纤中色散和非线性效应的表达式,对非线性薛定谔方程进行归一化处理并求解,获得光子晶体光纤中基态孤子解.在远大于光纤零色散波长区域,使色散和非线性效应达到平衡,在光子晶体光纤中就可以得到稳定的光学孤子.光子晶体光纤中产生的孤子可以作为光孤子通信的载波,是光子晶体光纤中高次谐波产生的泵浦源.According to the nonlinear Schrodinger equation of the optical pulse propagation in photonic crystal fiber, it is analyzed that the basic principle of soliton, the optical pulse expression, is given that the dispersion and nonlinear effects in photonic crystal fiber, the nonlinear Schrodinger equation, is normalized, and the ground state soliton solution is obtained in the photonic crystal fiber. In the wavelength region far greater than the fiber zero dispersion, the balance between the dispersion and nonlinear effects in photonic crystal fibers is achieved, and the stable optical soliton can obtained. The generation of soliton in photonic crystal fiber can be used as cartier of optical soliton communication, and is the pumping source in high order harmonic generation in photonic crystal fiber.
