Abstract

This study proposes a dual-channel surface plasmon resonance (SPR) sensor integrated on a wedge-shaped optical fiber end-face, which can detect two parameters: temperature and refractive index. The sensor adopts a unique double-surface design, both coated with gold films. One surface is used for the SPR excitation, while the other serves only as the reflection surface. By adjusting the wedge angle of the wedge-shaped end-face, the angle of the incident light can be adjusted, thereby influencing the sensitivity of the entire sensor. Through simulation, an optimal wedge angle of 4° was selected. The excitation surface of the wedge-shaped optical fiber was divided into two sections for temperature and refractive index measurement, respectively. Within the temperature range of 30–45 °C, the temperature sensitivity was −4.013 nm/°C. Within the refractive index range of 1.33–1.38, the sensitivity of 2607.8 nm/RIU was obtained. This study offers new insights for the development of multi-parameter-sensitive and compact optical fiber SPR sensors, which feature a reflective probe-type configuration and facilitate miniaturization.

楔形光纤端面集成的超紧凑温度和折射率双参数传感器

本研究提出了一种集成在楔形光纤端面上的双通道表面等离子体共振（SPR）传感器，该传感器可以检测温度和折射率两个参数。传感器采用独特的双面设计，两面都涂有金膜。一个面用于SPR激发，而另一个面仅作为反射面。通过调整楔形端面的楔形角度，可以调整入射光的角度，从而影响整个传感器的灵敏度。通过仿真，选择最佳楔角为4°。将楔形光纤的激发面分成两部分，分别进行温度和折射率的测量。在30 ~ 45℃温度范围内，温度灵敏度为−4.013 nm/℃。在1.33 ~ 1.38折射率范围内，获得了2607.8 nm/RIU的灵敏度。该研究为多参数敏感和紧凑型光纤SPR传感器的发展提供了新的见解，该传感器具有反射探针型配置，有利于小型化。

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.
