分步傅里叶法在光孤子传输中的数值研究

Study on the split-step Fourier method in soliton transform numerical analysis

本文详细介绍了分步傅里叶法的基本原理和仿真步骤,并用matlab语言对光孤子在光纤中的传输演化进行了仿真。讨论了光纤损耗对光孤子传输的影响。并说明当光孤子对在光纤中传播时,距离太近将会产生强烈的相互作用,导致孤子形状的畸变。最后文章对掺铒光纤放大器对孤子能量补偿作用做了探讨。

In this paper, the split-step Fourier transform method (SSFM ) is particularly introduced and the simulation is also given. We use matlab language to simulate the soliton propagation in the optical fiber. The influence of optical fiber waste is discussed and it also pointed that if two optical solitons are very near, they will strongly infect each other, it can make the soliton shape aberrant. In the last of the paper, the EDFA is discussed to compensate the power of the soliton.
