两类非线性薛定谔方程的调制不稳定性
The modulation instability of two kinds of nonlinear Schr?dinger equations
摘要
Abstract
Modulation instability plays a supporting role to explain some phenomena in many fields as a basic theory , such as nonlinear optical light w hich use it to explain and control the instability originate the interaction between the nonlinear term and dispersion parts . Instead of finding the mechanism of rogue wave's foundation , it is the modulation instability plays an important reason . In optical fiber communication modulation instability obtained the very good application in the dispersion management solitons .In this paper we start form two classes of nonlinear Schr?dinger equation and analyze their instability region , at the same time we give the gain spectrum graphics under the condition that with specific parameters and different amplitudes .关键词
