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 并分析了濾波器的線性色散和入射脈沖的啁啾大小對(duì)輸出脈沖的影響,對(duì)實(shí)際的光通信系統(tǒng)中器件參量的設(shè)計(jì)具有一定的指導(dǎo)意義。利用耦合模理論,對(duì)幾種典型的光纖光柵進(jìn)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 ) 對(duì)高能束流和電子回流構(gòu)成的雙流系統(tǒng),建立冷等離子體流體模型,采用簡(jiǎn)正模分析方法,分別考慮擾動(dòng)波矢在平行于電流傳播方向的平面(記為xy平面)上和在垂直于電流傳播方向的平面(記為yz平面)上這兩種情況,推導(dǎo)了不穩(wěn)定性的色散關(guān)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 而平場(chǎng)輸入輸出的edg在很多應(yīng)用中可以省去制作輸入輸出波導(dǎo),大大簡(jiǎn)化制作工藝;同時(shí)平場(chǎng)輸入輸出的edg能夠保持良好的線性色散和聚集效果。
