Abstract

In this paper, a three-parameter optic fiber sensor is proposed and demonstrated, which consists of double-clad fiber and a waist-enlarged taper structure. The transmission spectrum of the sensor has multiple independent resonance peaks and different sensitivity responses to different parameters. This optic fiber sensor has a simple structure and high mechanical strength, and the wavelength shift of three resonance peaks can be demodulated, and the coefficient sensitivity matrix can be used to measure multi-parameter measurements simultaneously. The experimental results show that the temperature resolution is 0.665 °C, the strain resolution is 500.812

μ ε

, and the refractive index resolution is 0.003 RIU.

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.
