| 摘 要： | 运用数值方法研究了色散缓变光纤中飞秒基本孤子的传输特性，发现基本孤子脉冲不仅能被压缩，而且压缩光脉冲能保持脉宽不变转输即稳定传。光脉冲压缩过程中，发现三阶色散效应有较大的影响。适当地选取色散缓变光纤结构参数可能获得高质量的超短压缩光脉冲。对压缩光脉冲稳定伟机理探索表明，光纤二阶色散纵向变化率，三阶色散与喇曼自散射效应共同作用导致压缩光脉冲稳定传输。

| Abstract: | Femtosecond soliton propagation in fibers with slowly decreasing dispersion(FSDD ) has been investigated by solving numerically the generalized nonlinearSchrodinger equation which includes the contributions of Kerr and Raman third ordernonlinearity. A pulse-width stabilized femtosecond pulse is discovered and described as aresult of the combined action of the third-order dispersion and Raman self-scatteringeffects. We also find that the third-order dispersion effect has much more important rolesin femtosecond Pulse compression. A nice train of high quality ultrashort pulses withpulse-width about 10 fs in the 1. 55 micron is obtained in the FSDD in which group speeddispersion (GVD) linearly decreases and the third- order dispersion is much smallcompared to GVD. |
