摘要

光纤折射率传感器在生物医学检测、食品化学等领域具有广泛的应用前景。为此，我们提出并研究了一种高灵敏度的超结构长周期光纤光栅（SLPFG）。该光纤结构由无芯光纤（NCF）和单模光纤（SMF）按照一定的调制函数周期性拼接而成，有效地激发了高阶包层模式，提高了RI的灵敏度。实验结果表明，该传感器在1.33 ~ 1.42的测量范围内，在557.74 nm/RIU处具有较高的RI灵敏度。SLPFG的总结构长度仅为5.4 mm，有利于集成应用。此外，该传感器具有良好的稳定性、重复性和较强的力学性能，在环境监测、生化监测、医学诊断等方面具有广阔的应用前景。

A highly sensitive refractive index sensor based on super-structured long-period fiber grating

Fiber refractive index (RI) sensor shows superiority in various applications including biomedical detection and food chemistry. Herein, we propose and investigate a super-structured long-period fiber grating (SLPFG) for RI measurement with the high-sensitivity. This fiber structure is composed of periodically spliced no-core fibers (NCF) and single-mode fiber (SMF) according to a certain modulation function, which effectively excites the high order cladding mode and improves the sensitivity of RI. Experimental results show that the sensor has a high sensitivity of RI at 557.74 nm/RIU in the measurement range of 1.33–1.42. The total structural length of SLPFG is only 5.4 mm, which is beneficial for integrated applications. In addition, the sensor achieves good stability, repeatability and strong mechanical properties, which has broad application prospects in environmental monitoring, biochemical monitoring, medical diagnosis and other aspects.

期刊介绍： Innovations in optical fiber technology are revolutionizing world communications. Newly developed fiber amplifiers allow for direct transmission of high-speed signals over transcontinental distances without the need for electronic regeneration. Optical fibers find new applications in data processing. The impact of fiber materials, devices, and systems on communications in the coming decades will create an abundance of primary literature and the need for up-to-date reviews. Optical Fiber Technology: Materials, Devices, and Systems is a new cutting-edge journal designed to fill a need in this rapidly evolving field for speedy publication of regular length papers. Both theoretical and experimental papers on fiber materials, devices, and system performance evaluation and measurements are eligible, with emphasis on practical applications.
