| 中文摘要: |
| 研究了截止频率低于发射场频率的单模光纤(@1550nm)中的传输模式,利用火焰熔融法制作了拉锥光纤,通过控制拉锥后的光纤尺寸,得到了632.8nm波长的单模输出.实验上观测了拉锥前后的模场分布. |
| 英文摘要: |
| The guiding modes of a single mode fiber(@1550nm),when the cutoff frequency of the fiber is less than the frequency of the launching field,have been investigated.The fused tapered fiber has been fabricated by using the flame of a spirit lamp.If controlling the fiber dimension well during pulling process,the unique tapered fiber will have a multimode input end and a single mode output end for launching wavelength 632.8nm,which are demonstrated in our experiment. |
