球端面径向梯度折射率激光－单模光纤耦合透镜的设计研究

Study and Design of Radial Gradient-Index Coupling Lens with Spherical Endfaces for A Laser Diode to Single Mode Fiber

本文研究径向梯度折射率透镜用作激光二极管－单模光纤耦合透镜的结构选型，探讨平－凸、凸－平型径向梯折耦合透镜的像差特性。通过比较认为平－凸型梯折耦合透镜更为可取。

In this paper,we study radial gradient-index lens employed as laser diode to single mode fiber coupling lens, including the comparison of the structure and the aberration characteristics of convex-plano between plano-convex radial GRIN coupling lens.It turned out that piano-convex lens have several advantange over convex-plano lens.
