| 摘 要： | 采用实验方法测量了球形光纤与楔形光纤的耦合效率,得出耦合效率随楔形光纤的楔角及球形光纤弓形高变化曲线.通过实验可得,楔形与球形光纤的耦合效率随楔角增加而增大,当楔角由20.6°增大到30.3°以及楔角由40.6°增大到55.2°时,耦合效率曲线呈较快速上升趋势,由30.3°增大到40.6°以及楔角由55.2°增大到76.5°时,耦合效率曲线上升趋势较缓;随着球形光纤弓形高的增加,球形与楔形光纤的耦合效率基本上线性上升;耦合效率随着楔形与球形光纤的间距的减小而增大,当间距由0.09mm减小到0.05mm时,耦合效率曲线呈较快速上升趋势,由0.04mm减小到0.01mm时,耦合效率曲线呈下降趋势.

| Abstract: | The coupling efficiency of spherical fibre optics and wedge-shaped fibre optics is measured by the experimental method.The curve reflecting that the coupling efficiency of fibre optics changes with the wedge angle of wedge-shaped fibre optics and the sagita of spherical fibre optics is given.By the experiments,the coupling properties had been analyzed and compared.It had been shown that coupling efficiency between a spherical fibre optics and a wedge-shaped fibre optics increases with the increase of wedge ... |
