梯度折射率纤维端面耦合成像元件的设计

Desing of gradient-index fiber lens for end-to-end coupling imaging

根据抛物型梯度折射率纤维透镜的近轴成像公式,分析了具有一定缩放倍率的梯度折射率纤维端面耦合成像的特性,探讨了这种纤维端面耦合成像元件的设计。

Based on the paraxial imaging formulas of a parabolic gradient-index fiber lens, the end-to-end coupling imaning characteristics of a parabolic GRIN fiber lens with magnification of β>1~x or β<1~x are analyzed. And the design of this fiber lens for end-to-end coupling imaging is discussed.
