| 摘 要： | 本文阐述了半导体激光放大器组件中,末端带高折射率类球透镜的锥形光纤耦合头对放大器芯片的外腔反馈效应,从理论上对这种耦合头的反馈效应进行了计算.为了使计算结果更接近于实际情况,在理论分析中引入了厚透镜表面的菲涅耳(Fresnel)反射及有限孔径的影响.

| Abstract: | In this paper, the feedback effect of tapered-fiber coupler with high reflective index miorolens on its top is described, which influences the property of travelling wave semiconductor laser amplifier. The theoretical analysis of the effect is presented with the Fresnel reflection on the surface of thick lens and the definite aperture introduced in the analysis to make the results agreement with the actual case. |
