| 摘 要： | 从含修正项的非线性薛定谔方程出发,采用变分法,导出了在三阶色散情况下光学高斯型脉冲参数随传输距离的演化方程组;在此基础上,求出了振幅与脉宽、频率与啁啾、脉宽与啁啾之间的三个重要约束关系;并进一步得出了脉宽随传输距离演化的解析解;讨论了三阶色散对光纤中高斯型脉冲传输特性的影响.

| Abstract: | The evolution equations for the parameters of the optical Gaussian-shaped pulse in optical fibers are derived by means of variational method from the MNLS equation. Then three important restricted relations between amplitude and width, frequency and chirp, width and chirp are obtaimed. Analytical solution about the width of pulse evolving on the propagation distance is also obtained. The influence of the third-order dispersion on the propagation properties of optical gaussian-shaped pulses in optical fibers is discussed. |
