| 摘 要： | 本文通过幂级数法和逐差法对不同形式圆对称光栅微腔结构中的光场分布进行模拟,验证各自的适应范围及正确性。模拟表明光栅可以改变微腔中的光波,合理地选择轴心高折射率区的半径及外围光栅的形状和参数,可以增加模式间隔和有源区内基模光波能量的比例,从而提高选模性能。

| Abstract: | The light wave distributions in micro cavity with circular grating have been analyzed byusing power series and successive difference methods in this paper. They were tested and verifiedcorrectly in different application ranges . If we correctly choose the value of the radius of activemedium and the grating around it,the mode discrimination would be increased. |
