Abstract

An ultra-compact Fabry-Pérot (FP) interferometer integrating a microbubble with polydimethylsiloxane (PDMS) end-cap is fabricated with physical wrapping and fusion splicing methods for sensing ambient temperature. The mechanically robust polymer cap has an average diameter of 0.5 cm. The end-capped sensor exhibits a high temperature sensitivity of −6.818 × 10⁻² dB/°C, which is 10 times higher than that of the sensor composed of only microbubble without PDMS encapsulation. Due to its simple fabrication technique, high sensitivity, fast response, and good stability, the temperature sensor has significant potential in the bio-pharmaceutical, chemical, and environmental industries.

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.
