| 中文摘要: |
| 侧边抛磨多模光纤(SPMMF)与侧边抛磨单模光纤(SP SMF)相比,具有工艺上容易实现的优势。为了研制SPMMF传感器,分析SPMMF中光功率传输特 性,首先利用有限差分 光束传输法(BPM)模拟计算了不同剩余半径SPMMF中的光强、模场分布以及光纤中传输光 功率与抛磨区覆盖材料折射率的关系,并进行了实验验证。实验结果与模拟结果相互吻合: 当抛磨区覆盖 材料折射率小于1.440时,光功率透过率接近在空气中的透过率；当 覆盖材料的折射率逐渐增大到1.458时, 光功率透过率减小到最小值,且最小值不小于0.001；当覆盖材料的 折射率大于1.458时,光功率透过率由最 小值逐渐增大,最终维持在一个相对稳定的值；不同剩余半径的SPMMF中的传输光功率透过 率不同,剩余半径越小,SPMMF中传输光功率透过率越小。 |

| So SPMMF is easier to be implimented t echanically compared with the side polished singlemode fiber. To develop side polished multimode fiber (SPMMF) sensor,the optical power transmitting characteristics in SPMMF are analyzed.First we utilize BPM to simul ate and calculate the distribution of light intensity and mode field in SPMMF with different remaining radii,and the relation between the transmitted light power in fiber and the index of refraction of cover material i n polished area is derived as well.furthermore,we demonstrate our conclution wit h experiment.The results show that when the index of refraction of cover materia l in polished area is smaller than 1.44,the transmittance of light power in fiber is close to the transmittance in air; When the index of refraction of cover material in polished area increases to 1.458,the transmittance decreases to the minimum,and the minimum is not less than 0.001;When the index of refraction of cover material in polished area is lager than 1.458,the transmittance increases slowly and remains at a relatively stabl e value.The transmittance of the transmitted light power in SPMF will be affected by remaini ng radius.We conclute that the transmittance of the transmitted light power in SPMF is smaller as the remaining radius is smaller. |
