| 摘 要： | 平板波导内的场按自由空间传播的厄米高斯函数展开，计算了平板波导谐振腔的耦合损失，给出了平板波导中ＥＨ１１模的耦合损失与球镜的曲率及位置的关系。结果表明存在两种特定的结构使耦合损失最小。

Hermite-Gaussian Expansion Theory on Coupling Losses in Planar Waveguide Resonators |
| |
| Abstract: | A Hermite-Gaussian expansion is used to calculate the optical wave propagation between the planar waveguide and the reflector. The coupling losses in planar waveguide resonators are calculated and the coupling losses for the EHo mode of different planar waveguide as a function of mirror curvature and position are presented. It is shown that there exist two special geometries having low coupling losses. |
