| 利用微纳光纤强的倏逝场特性和平面光栅的折射 率周期性分布特性,设计了一种新型 的基于微纳光纤和平面光栅复合光波导折射率传感器,并利用时域有限差分(FDTD)方法,对 复合光波导的光学特性和 折射率传感特性进行了仿真研究。结果表明,本文的复合光波导的透射光谱中心波长对其周 围物质折射率变化非常敏感,灵敏度为346nm/RIU(refractive inde x unit)。 |
| 英文摘要: |
| In this paper,by taking advantage of the micro/nanofiber′s strong ev anescent field and the plane grating′s refractive index periodically distributed properties,a refractive i ndex sensor based on a composite waveguide composed of a micro/nanofiber and a plane grating is innovatively desi gned.And then,by using the finite difference time domain (FDTD) method,the optical and refractive Index sen sing properties of the composite optical waveguide are studied in simulation.The results show that the center wav elength of waveguide′s transmission spectrum is very sensitive to the surrounding mater ial refractive index variation and the refractive index detection sensitivity is 346nm/RIU (refractive index unit). |
