Simultaneous measurement of strain and temperature based on PDMS sealed NCF offset sensor
An optical fiber Mach-Zehnder interferometer (MZI) is designed and demonstrated for the simultaneous measurement of strain and temperature. One microcavity fabricated by no-core-fiber (NCF) offset splicing is used to generate two different light paths for MZI, then sealed with polydimethylsiloxane (PDMS) to enhance the strain and temperature sensing ability. The strain and temperature sensing characteristics were simulated theoretically and investigated experimentally. The maximum strain sensitivity of −16.3 pm/μɛ was obtained in the range of 0–500 μɛ, and the ultrahigh temperature sensitivity of 10.45 nm/℃ was obtained in the range of 20–40 °C. The influence of microcavity length was analyzed in detail and the dual-parameter demodulation was demonstrated by solving a two-dimensional sensing matrix. The designed sensor with the merits of simple structure, easy fabrication and highly sensitive to weak strain and temperature, make it of great potential for the structural safety monitoring or wearable strain and temperature detections.
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.
