| 摘 要： | 利用傅里叶变换法,首次推出了单模光纤正常色散区中二阶、三阶色散共同决定群速度色散效应时,所致啁啾的解析表达式.利用数位解法,模拟了零色散波长附近群速度色散效应和自相位调制效应共同导致的啁啾演变过程.计算结果表明:啁啾为非线性的,且有极值,因而导致脉冲形状的畸变.

| Abstract: | Taken into account second and third order dispersion in the normal - dispersion region ofsingle-mode fibers by means of Fourier-transform algorithm,an analytic expression of the dispersioninduced chirp is obtained. The results show that chirp is nonlinear and has extreme value,it is shownthat pulse distortion is induced by chirp. |
