| 摘 要： | 微结构的光子晶体光纤，通过填充光敏等功能材料，具有可调谐、全光纤结构和易于集成等优点，是光纤光子器件发展的重要方向.毛细管法将高折射率的匹配液，填充到空心光子晶体光纤中邻近纤芯的空气孔中，两端熔接单模光纤，制成高灵敏的应变传感器.实验表明，当填充30mm长，折射率为1.508的匹配液时，测得应变灵敏度约为每应变4.36pm.实验结果与仿真结果相符，这种装置可用于高灵敏的应变传感.

| Abstract: | Functional materials infiltrated photonic crystal fibers are optical devices that are wavelength tunable,all in fiber structure and easy to be integrated into optical systems,and have been a prominent research focus in optical fiber pho-tonic devices.A highly sensitive strain sensor is made by selectively infiltrating high refractive index matching liquid into the air holes adjacent to the fiber core of a hollow core photonic crystal fiber (PCF)by capillary force,and splicing single mode fibers at both ends of the PCF.A strain sensitivity of 4.36pm/μεis obtained by a device with infiltration length of 30mm and liquid refractive index of 1.508.The experimental results agree well with the simulation predictions.Such a device can be used for strain sensing with high sensitivity. |
