| 摘 要： | 通常是在时域上求解非线性薛定谔方程来研究光纤中超短光脉冲传输特性,然而对于超连续(SC)谱产生问题,由于SC谱的频谱宽,光纤色散与光波频率有关,因而时域中的非线性薛定谔方程不能给出精确的描述.从频域上实现超短光脉冲在光纤中传输所满足的全场方程出发,理论分析了实现SC续谱研究的具体形式,并以色散平坦缓变光纤为例,对其中的SC谱产生进行了具体研究.

| Abstract: | Nonlinear Schrdinger equation in the time domain is often solved, when ultrashort pulses are propagated in fibers. But Supercontinuum(SC) generation can't be described exactly in this way, because the bandwidth of SC spectrum is so wide that dispersion of fibers relates to the optical frequency. In this paper, the concrete form for study of Supercontinuum generation is deduced from the total field formulation in the frequency domain. Then as a case, Supercontinuum generation in a dispersion-flattened/decreasing fiber is studied in detail. |
