摘 要: 提出一种制备全光纤型液芯微结构光纤的方法,首先用飞秒激光在多模光纤的端面进行开槽处理,然后将开槽后的多模光纤与微结构光纤熔接,所开的槽在微结构光纤的两端形成用于液体填充的开孔,在液体填充后采用胶封的方式将填充液体密封在微结构光纤的气孔中,对制备后的全光纤型液芯微结构光纤的荧光波长、荧光强度和自参考强度与温度之间的关系进行分析。利用该结构,通过在不同段微结构光纤中填充荧光波长不同的量子点溶液,构建基于量子点填充的复用式微结构光纤温度传感器,分析该传感器波分复用结构和温度传感特性,该结构的提出有望为光纤传感器的多点测量提供新的思路。

Abstract: We propose a method for the fabrication of all-optical fiber liquid core microstructure optical fiber. Firstly, a groove is carved on the end-face of the multi-mode optical fiber by use of femtosecond laser. Secondly, the carved multi-mode optical fiber is fused to the microstructure and then the carved groove is used for filling. At last, the filled liquid is encapsulated in the holes of the microstructure optical fiber. The relationship of the fluorescent wavelength, fluorescent intensity and self-reference intensity with temperature is analyzed. With this structure, the quantum dots solution with different fluorescent wavelengths is filled into microstructure optical fiber, the multiplexing microstructure fiber temperature sensor is constructed based on quantum dots filling. Both the wavelength division multiplexing and temperature sensing characteristics of the sensor are analyzed. The proposed sensor hopefully provides new thought for multi-point measurement of optical fiber sensor.
