光孤子在单模光纤中零色散附近的传输特性

Behavior of Soliton in the Neighborhood of Zero-dispersionPropagation in a Single Model Optical Fiber

该文用分步付里叶方法对中心波长在零色散附近的超短光脉冲在单模光纤中的传输行为进行了数值求解．结果表明,N=1的类基孤子形状基本不变,而N=2或3的类孤子的形状有分离现象产生.

Abstract: In this paper, the behavior of extreme picosecond pulse with wavelength neighborhood of the zero-dispersion propagating in a single-model optical fiber are solved numerically by using the split-step Fourier method. It is showed that the solitonlike pulse with N = 1 appears well behaved and the solitonlike pulse with N = 2 or 3 appear separated.
