Modulation instability in fiber grating with nonlinearity management is studied based on the nonlinear coupled-mode equations. The dispersionrelation for modulation instability is obtained.
基于非线性耦合模方程，研究了非线性管理光纤光栅中的调制不稳定性，得到了调制不稳定性的色散关系。

Secondly, from the new dispersionrelation we get the gain spectrum for modulation instability in nonlinearity management fiber Bragg grating, and we compared it with normal nonlinear fiber grating.
