用实验方法测量了楔形光纤与锥形光纤的耦合效率,作出耦合效率随楔形光纤的半楔角及锥形光纤半圆锥角的变化曲线。从实验结果可以看出,楔形与锥形光纤的耦合效率随半楔角增加而增大。当半楔角由15.0°增大到30.3°,半楔角由44.9°增大到55.2°时,耦合效率曲线呈较快的上升趋势;当半楔角由30.3°增大到44.9°时,耦合效率曲线上升趋势变缓。当锥形光纤半圆锥角增加时,耦合效率也随着增大;并且随着楔形与锥形光纤的间距的减小而增大,在间距由0.10mm减小到0.03mm时,耦合效率曲线呈较快的上升趋势;在间距由0.03mm减小到0.01mm时,耦合效率曲线呈下降趋势。 The coupling efficiency between wedge fiber and taper fiber was measured experimentally, and the coupling efficiency was obtained with the half wedge angle of taper fiber and the half cone angle of taper fiber. It can be seen from the experimental results that the coupling efficiency of wedge-shaped and tapered optical fibers increases with increasing half-wedge angle. When the half-wedge angle increases from 15.0 ° to 30.3 ° and the half-wedge angle increases from 44.9 ° to 55.2 °, the coupling efficiency curve shows a rapid upward trend. When the half-wedge angle increases from 30.3 ° to 44.9 °, Coupling efficiency curve slows down. The coupling efficiency increases with the increase of the semi-cone angle of the tapered fiber and increases with the decrease of the distance between the wedge and tapered fiber. When the pitch decreases from 0.10mm to 0.03mm, the coupling efficiency curve Showing a rapid upward trend; when the spacing decreases from 0.03mm to 0.01mm, the coupling efficiency curve shows a downward trend.
