拉曼效应与光孤子通信

Raman Effect and Optical Soliton Communication

光纤孤子通信是一种非线性全光通信,它克服了光纤色散和电子设备响应速度慢等缺点,具有不损失波形,不改变速度,保真度高等优点。在光孤子通信中,一些重要问题是由 Raman 效应来解决的。如光纤受激 Raman 放大是根据光纤中的受激 Raman 效应对光孤子进行能量补偿。本文较为系统地介绍 Raman 效应与光孤子通信。

Optical soliton communication is a nonlinear all—optical communi- cation.It overcomes optical fiber dispersion and slow response of electron de- rices and it posses pulse—envelop reservation,velocity maintining,high fidli- ty.In optical soliton communication,some important problem are solved by Ra- man effect,such as:fiber stimulated Raman amplification compensates soliton energy by stiulated Raman effect.In this paper,Raman effect and optical soil- ton communication are systemly introduced.
