Abstract

The temperature-sensitive performance of tapered optical fibers, characterized by high sensitivity and stability, is comprehensively studied. This sensor, based on the coupling between core and cladding modes resulting in Mach-Zehnder interference (MZI), adopts a single-mode fiber (SMF)-multimode fiber (MMF)-tapered SMF-MMF-SMF (SMTMS) hybrid structure. The relationship between resonance wavelength shifts and surrounding temperatures is explored to evaluate its temperature sensitivity. Experimental results reveal that the multimode fiber length and the length of the conical region are critical factors affecting temperature sensitivity. Various SMTMS structures with differing MMF lengths and conical region lengths are fabricated, achieving a maximum sensitivity of −145.8 pm/°C. Notably, the sensor exhibits exceptional stability under laboratory conditions, further demonstrating its reliability for practical applications. With its high sensitivity and robust stability, this sensor shows great promise for applications in fields such as healthcare and environmental monitoring.

锥形光纤温度依赖性的研究

对具有高灵敏度、高稳定性的锥形光纤的温度敏感性能进行了全面研究。该传感器采用单模光纤(SMF)-多模光纤(MMF)-锥形SMF-MMF-SMF （SMTMS）混合结构，利用芯模和包层模式之间的耦合导致马赫-曾德尔干涉（MZI）。探讨了共振波长位移与周围温度的关系，评价了其温度敏感性。实验结果表明，多模光纤长度和锥区长度是影响温度灵敏度的关键因素。制备了具有不同MMF长度和锥形区域长度的各种SMTMS结构，最大灵敏度为- 145.8 pm/°C。值得注意的是，该传感器在实验室条件下表现出优异的稳定性，进一步证明了其在实际应用中的可靠性。该传感器具有高灵敏度和强大的稳定性，在医疗保健和环境监测等领域的应用前景广阔。

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.
