| 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FPI（Fabry-Perot interferometer）传感器，形成SMF-PCF-SMF结构，其中PCF为FP腔。反射谱波长周期为2.18 nm，条纹对比度达到 13.12 dB。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 12.3 pm/℃，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。 |
| 英文摘要: |
| 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), preparing a SMF-PCF-SMF structure, and the section of PCF was the cavity. The spectrum wavelength interval was 2.18 nm and its contrast was up to 13.12 dB. Temperature was investigated experimentally in the range of 50 ℃ ~ 400 ℃ with temperature-rise and temperature-drop process. The temperature 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, making it attractive in the areas of industrial production, aerospace and biomedicine. |
