  2. Based on the semi - vector wave equation under cylindrical coordinate system , the mode distribution and complex propagation constant in bent waveguides were computed by a finite difference method with perfectly matched layer ( pml ) boundary condition
    摘要以柱坐标下的半矢量波动方程为基础,采用基于完美匹配层( pml )边界条件的有限差分方法,对弯曲波导进行模式求解,进而得到波导弯曲引起的辐射损耗。
  3. In this work , based on the threshold condition of the fiber grating external cavity semiconductor laser ( fgesl ) which the phase of the fiber grating has been included , the effect of the temperature variation and the fg external cavity length on the lasing wavelength of the fgesl has been investigated theoretically . in addition , we have used the phase condition of fgesl to get the longitudinal mode distribution of fgesl , then the influence of the injected current on the output characteristics of fgesl has been studied
    基于此,本文中利用阳实际的反射相位分布,计及半导体激光器( ld ) 、外腔及光纤光栅( fg )三者的共同作用,根据fgesl满足的闽值条件,从理论上研究了温度及外腔长度的变化对fgesl激射波长的影响;根据fgesl中纵模所满足的相位条件得到其纵模分布后,利用fgesl满足的多模速率方程,研究了ld的注入电流对fgesl输出特性的影响。
  4. In present studies of fgesl , the theoretical models usually neglected the contribution of external cavity and fiber grating to the phase condition , and considered the mode distribution of fgesl is in accordance with the mode distribution of ld without fg external cavity . obviously , such process method deviates from the physical facts
    在已有的对fgesl的研究中,所采用的理论模型均忽略了光纤光栅( fg )的反射相位及光线在外腔中的往返相移对模式分布的影响,认为fgesl的模式分布跟没有fg中文摘要外腔时ld的模式一致,这种处理方式显然违背了物理事实。
