| 中文摘要: |
| 基于薄膜微纳光纤中传播光能量分布的理论,在实验研究基础上,进一步用模场分析仪观察微纳光纤在表面镀有碳纳米管薄膜包层后,与丙酮气体接触时,其传输光的能量分布规律和倏逝场的变化。实验可知,在一定浓度的丙酮环境下,没有碳纳米管薄膜包层时,微纳光纤中传输光能量呈对称分布,当有碳纳米管薄膜包层时,其能量分布不再对称,并且能量分布的直径宽度增加。 |
| 英文摘要: |
| Based on the theory and experiments of energy distribution in the cladding microfiber,this paper studies the change in the light energy distribution and evanescent field of the microfiber coated carbon nanotubes(CNTs) films when it is exposed to acetone gas.The results reveal that the uncoated fiber shows symmetrical energy distribution under certain gas environment,while in the same gas environment,for the microfiber coated CNTs films,there is an increase in its width of the output light energy,and its energy distribution is unsymmetrical. |
