摘要
该文详细介绍了matlab及其建模仿真工具simulink的功能、特点和使用方法。并着重论述了如何利用simulink研究非线性光纤光学中的受激喇曼效应 ,指出在光纤通信中SRS遵从特殊的增长规律 ,并不具有“阈值”特性。Stokes束的增长不仅依赖于泵浦波的强度 ,而且也和自身的强度有关系。即使泵浦功率比较弱 ,SRS的影响也可能会存在。
In the paper, the function, characteristic and operation method of matlab simulink have been introduced briefly.The study of SRS in non-linear optic fiber by simulink emphatically. SRS comply with the special growth law,does not have“ threshold ”characteristics.It depends not only on the intensity of pump beam but also on the intensity of Stokes beam itself.Even if the intensity of pump beam is weak,the SRS effect is maybe still take place.
