Abstract

By using the hydrofluoric acid uniform-etching and step-etching methods, a tilted fiber Bragg grating (TFBG) microfiber structure was fabricated, where the cladding diameter of the traditional TFBG was reduced to micrometer scale. The temperature sensing characteristics of the uniform-etched and step-etched microfiber TFBGs were experimentally studied and compared. The core mode of its transmission spectrum was used for sensing the temperature change; while the normalized area of cladding modes has been used for real-time monitoring the liquid level. The simultaneous measurement of temperature and liquid level has been experimentally demonstrated for the proposed microfiber TFBG. By combining the strong evanescent field of microfiber and the unique structural advantages of TFBG, the proposed microfiber TFBG has a great potential in developing the miniature optical fiber sensors.

基于均匀和阶跃蚀刻超细纤维 TFBG 的温度和液位传感器的传感性能比较

利用氢氟酸均匀蚀刻法和阶跃蚀刻法制作了倾斜光纤布拉格光栅（TFBG）微纤维结构，将传统 TFBG 的包层直径缩小到微米级。实验研究并比较了均匀刻蚀和阶跃刻蚀微光纤布拉格光栅的温度传感特性。其透射光谱的核心模式用于感测温度变化；而包层模式的归一化面积则用于实时监测液位。实验证明，所提出的超细纤维 TFBG 可同时测量温度和液位。结合超细纤维的强蒸发场和 TFBG 的独特结构优势，所提出的超细纤维 TFBG 在开发微型光纤传感器方面具有巨大潜力。

期刊介绍： The Journal covers the entire field of infrared physics and technology: theory, experiment, application, devices and instrumentation. Infrared'' is defined as covering the near, mid and far infrared (terahertz) regions from 0.75um (750nm) to 1mm (300GHz.) Submissions in the 300GHz to 100GHz region may be accepted at the editors discretion if their content is relevant to shorter wavelengths. Submissions must be primarily concerned with and directly relevant to this spectral region. Its core topics can be summarized as the generation, propagation and detection, of infrared radiation; the associated optics, materials and devices; and its use in all fields of science, industry, engineering and medicine. Infrared techniques occur in many different fields, notably spectroscopy and interferometry; material characterization and processing; atmospheric physics, astronomy and space research. Scientific aspects include lasers, quantum optics, quantum electronics, image processing and semiconductor physics. Some important applications are medical diagnostics and treatment, industrial inspection and environmental monitoring.
