| 摘 要： | 本文研究了增益波导垂直腔面发射激光器的横向及纵向模式特性。采用二维延伸抛物型复折射率波导结构从理论上分析了增益波导垂直腔面发射激光器中模式的横向电场分布、模式间隔、模式增益对远场分布图和光束发射角、耦合效率等.实验中在阈值电流之上既观测到稳定的基模工作,也观测到高阶非简并模工作等不同的光谱结构及远场分布,理论和实验基本吻合. |

| Abstract: | The mode behavior in gain-guided vertical cavity surface emitting lasers has been studied. Using 2D stretch parabolic waveguide structure,some mode characteristics have been given in theory such as longitudinal and transverse mode spacing.far and near-field patterns.beam divergence and coupling effect.Fundamental mode and two-order mode have been observed in experiments.The experiments are in good agreement with the theoretical results. |
| Keywords: | Gain-guide VCSEL Mode behavior |
