摘　　要：从非线性薛定谔方程出发，研究了理想光纤，普通光纤，色散缓变光纤和色散阶梯式光纤的调制不稳定性，作为实际的应用，随着阶数的增加，色散阶梯式光纤几乎等价于色散缓变光纤。On the base of nonlinear schrodinger equation, the modulation instabilities are studied in ideal fiber, average fiber, dispersion decreasing fiber and step wise decreasing dispersion profiles fiber, As an application, we show that step wise decreasing dispersion profiled fiber is almost equivalent to the dispersion decreasing fiber when the step is increased.
