| 摘 要： | 给出了色散阶变光纤中群速度色散效应导致的啁啾表达式，采用数值方法模拟了该光纤中的啁啾演变过程。研究结果表明：色散阶变光纤中的啁啾以色散缓变光纤中啁啾为中心跳跃式变化，逐渐与色散缓变光纤中啁啾重合，且比常规光纤中的啁啾小。

| Abstract: | An analytic expression is obtained for the chirp induced by the dispersion in the stepwise decreasing dispersion fiber. Using numerical method, we simulate the evolution of chirp in the stepwise decreasing dispersion fiber. The results show that the chirp in the stepwise decreasing dispersion fiber varies jumply taking the chirp in the fiber of slowly decreasing dispersion as the centre at the beginning, then the chirps coincide gradually with each other. However the chirp in the stepwise descreasing despersion fiber is smaller than the chirp in the conventional fiber. |
