As a result , the peak power , pulse width and time delay of the output pulse have been investigated in detail , including the chirp of the input pulse and the linear dispersion of the filter , and some new and important conclusions have been obtained for the first time 并分析了滤波器的线性色散和入射脉冲的啁啾大小对输出脉冲的影响,对实际的光通信系统中器件参量的设计具有一定的指导意义。利用耦合模理论,对几种典型的光纤光栅进行了研究。
Using the two - stream fluid model , the linear dispersion relation is derived assuming a two - dimensional spatial geometry . two cases are considered , one is that the 2d spatial geometry is defined by the plane containing the two counterstreaming electron populations and the perturbation wave vector ( referred as the xy plane ) , and the other is that the geometry is defined by the plane being vertical to the two counterstreaming electron populations ( referred as the yz plane ) 对高能束流和电子回流构成的双流系统,建立冷等离子体流体模型,采用简正模分析方法,分别考虑扰动波矢在平行于电流传播方向的平面(记为xy平面)上和在垂直于电流传播方向的平面(记为yz平面)上这两种情况,推导了不稳定性的色散关系。
For example , in some applications an edg without input and output waveguides is preferable and it is much easier to fabricate . an edg of flat input / outputs can also maintain a good linear dispersion and a perfect focused field as a conventional edg this paper presents a design method for an edg of flat input / outputs is presented 而平场输入输出的edg在很多应用中可以省去制作输入输出波导,大大简化制作工艺;同时平场输入输出的edg能够保持良好的线性色散和聚集效果。
