Specialty optical fibers for advanced sensing applications

 

Optical fiber technology has changed the world in enabling extraordinary growth in world-wide communications and sensing. Optical fiber sensors offer favorable advantages such as immunity to electromagnetic interference, lightweight, small size, high sensitivity, large bandwidth, reliable and robust performance, ability to withstand harsh environment, and ease in implementing multiplexed or distributed sensors. To date, optical fiber sensors have been widely used and explored for civil engineering, environmental monitoring, agricultural engineering, biomedical engineering, etc. Notably, the research on specialty optical fibers is playing a critical role in enabling and proliferating the optical fiber sensing applications. Special fiber sensing technology includes various types of fiber, such as single-mode fiber, multi-mode fiber, multi-core fiber, fiber grating, microstructure fiber, etc. Compared with traditional optical fiber sensors, sensor performance such as sensitivity could be significantly improved by utilizing specialty fiber-based sensors.

A review article named "Specialty Optical Fibers for Advanced Sensing Applications" was published in Opto-Electronic science by Professor Perry Ping Shum’s research team in the Optoelectronics Intellisense Lab of Southern University of Science and Technology Issue 2, 2023. The paper overviews recent developments in specialty optical fibers and their sensing applications. The specialty optical fibers are reviewed based on their innovations in special structures, special materials, and technology to realize lab in/on a fiber. An overview of sensing applications in various fields is presented. The prospects and emerging research areas of specialty optical fibers are also discussed.

Wearable sensing technologies have benefitted from the development of specialty optical fibers, ranging from fiber microstructure-based sensors, fiber interferometer-based sensors, polymer optical fiber (POF) sensors and micro/nano fiber (MNF) sensors. Optical fiber shape sensors based on special fibers and fibers with advanced structures have achieved performance enhancement and attracted growing interest in developing applications in medical treatment, soft robots, and structural behavior monitoring. Besides point sensing applications, distributed fiber sensors have been widely used for industrial applications, such as monitoring of gas pipelines, underwater security, loaded beam structure, earth phenomena, power transformer and downhole environments. Specialty fibers are also widely used in biosensor instrumentation for life sciences related clinical, and research applications.
