摘要
碳基材料聚合物拥有增强光纤传感器传感特性的潜力。将碳基材料与光子晶体光纤(PCF)相结合,先将剥除涂覆层的PCF两端与同样剥去涂覆层的单模光纤(SMF)熔接在一起,然后在结构表面涂覆石墨烯层,形成一个基于PCF的马赫-曾德尔干涉仪(MZI)。实验证明,在基于PCF的干涉仪传感器表面涂覆石墨烯材料能够提升传感器的折射率灵敏度。
Carbon-based material polymers have the potential to enhance the sensing characteristics of fiber-optic sensors. Combining the carbon-based material with the photonic crystal fiber（PCF）, the PCF stripped with the coating layer is first fused with the single-mode optical fiber stripped with the coating layer, and then the graphene layer is coated on the surface of the structure to form Mach-Zehnder interferometer based on PCF. The experiment proves that the refractive index sensitivity of the sensor can be improved by coating the graphene material on the surface of the interferometer sensor based on the photonic crystal fiber.
