摘要
提出了一种将光子晶体光纤(Photonics Crystal Fiber,PCF)与单模光纤(Single Mode Fiber,SMF)拼接而成的法布里-珀罗干涉(Fabry-Perot Interferometer,FPI)传感器,形成SMF-PCF-SMF结构,其中PCF为F-P腔。反射谱波长周期为2.18nm,条纹对比度达到13.12dB。研究了FPI传感器的温度响应,在50~400℃分别进行了升温和降温实验,波长灵敏度为12.3pm/℃,线性度大于0.993。该传感器具有交叉灵敏度低、温度稳定性好、线性度高等优点,可用于工业生产、航空航天、生物医学等温度传感领域。
The paper proposed and studied a Fabry-Perot interferometer (FPI) sensor by splicing a photonic crystal fiber (PCF) to a well-cleaved single-mode fiber (SMF) and preparing a SMF-PCF-SMF structure in which the section of PCF is the cavity.The spectrum wavelength interval is 2.18 nm and its contrast is up to 13.12 dB.The temperature response of the FPI sensor was investigated experimentally in the range of 50 ~ 400 ℃ with temperature-rise and temperature-drop process.The wavelength sensitivity is 12.3 pm/℃ and its linearity is greater than 0.993.The proposed sensor could offer some excellent features such as low cross-sensitivity,good temperature stability and linearity,which makes it attractive in the areas of industrial production,aerospace and biomedicine.
