| 摘 要： | 从理论和实验两方面研究了多模锥形光纤锥端的特性。用射线理论分析了不同锥角大小条件下锥端光线传输特性，推导出了锥角大小与锥端孔径角及出光发散角的关系。按照理论指导制备了不同锥角的银行光纤，通过激光二极管与锥形光纤耦合等实验验证了理论的正确性。

| Abstract: | The properties of multimode tapered fiber end are studied in this paper. Based on light ray theory the transmission property of the tapered fiber end on different tapered angle is analyzed. The tapered end aperture angle versus the tapered angle and the tapered end radiation angle versus the tapered angle are obtained through the analysis. Finally a best design for coupling has been suggested. In the experiment,according to the theory analysis tapered fibers of different angle are fabricated by means of melting and pulling the end of optical fiber. The correctness of the theory is vadicated through the experiments. |

| Keywords: | tapered fiber aperture angle light radiation angle coupling efficiency |
