摘要

    摘要
  • 摘要: 传统光纤包层中仅存在泄漏的倏逝波，能量较小，不利于包层传感的应用。增大包层中的能量，实现整体包层导光是提高光纤传感灵敏度的有效途径。从理论上分析了利用空芯带隙型光子晶体光纤(HC-PCF)包层进行导光的机理。在实验上选用带隙外的冷光源和激光对一种典型结构的HC-PCF进行了空气孔包层的导光实验，并利用折射率引导型光子晶体光纤和单模光纤进行对比实验。结果表明，带隙范围外光波在HC-PCF中传输时将不受禁带效应的约束泄露至包层中重新分布。包层中SiO2与空气孔的周期型结构将光波约束在高折射率介质中，实现HC-PCF整体空气孔包层中光波的稳定传输。PBG-PCF包层的整体导光在传感上有提高灵敏度的潜在价值。
    Abstract: Conventional fiber cladding only has leaking evanescent wave with low energy, which prevents the application of cladding sensing. Guiding light in the full cladding is expected to improve the sensitivity of hollow-core photonic crystal fiber (HC-PCF) application for material sensing. An approach to increase the energy transmitting in the cladding was theoretical analyzed. The light guidance experiments of air-hole cladding of HC-PCF were carried out by using a cold light source and a laser. The contrast experiments between total internal reflection-photonic crystal fiber (TIR-PCF) and single-mode fiber (SMF) were done. The results indicated that, by choosing appropriate wavelength, the light in HC-PCF leaked entirely into the cladding and propagated in the air-suspended silica cores between the air holes, which was different from TIP-PCF and SMF-28.
