Special Issue Information

Dear Colleagues,

In the 1960s, Dr. Charles Kuen Kao (The Nobel Prize Winner of Physics 2009) discovered optical fibers, which were multimaterial silica fibers in a broad sense with a higher refractive index of doped silica cores and a relatively lower refractive index of pure silica claddings. Multimaterial silica fibers open a new door for transmitting light and information to thousands of homes by total internal reflection at the core/cladding interface. Furthermore, increasing efforts have been made to develop the field of optical fiber networks and optical data communications, which has become an indispensable part of modern life. With the development of optical fiber theory and multimaterial fabrication techniques, in the last three decades, multimaterial fibers have witnessed outstanding improvement. Many new multimaterial fibers have been discovered, motivated by the novel concept of “Special functional fiber”, fiber-drawing dissimilar core-clad composite technologies, and in-fiber crystallization mechanisms. Although most of these fibers are used for “conventional” telecommunication applications, there is a growing need for multimaterial fibers relevant in other applications, such as light generation using fiber lasers, remote sensing, nonlinear optics, medicine and health, laser imaging, and so on. Aiming at the practical application of multimaterial fiber technology, more research has been undertaken in the design and fabrication of multimaterial fiber devices in recent years. However, many scientific and engineering problems still need to be solved. If the multifunctional materials can be integrated into multimaterial fibers and devices, the multifunction will be transmitted to thousands of homes.

It is high time to collect high-quality studies or reviews to highlight the cutting-edge development of multimaterial fibers and discuss the device applications of multimaterial fiber technology. In this Special Issue, we welcome research on multimaterial fibers and devices, including, but not limited to, the discovery of new fiber materials by preparing glass-clad/polymer multimaterial fibers and designing fiber-based devices comprising conductor, semiconductor, single crystal, polycrystal, nanocrystal, quantum dot, low-temperature glass, rare-earth ions doped core glass, and dissimilar core-clad materials.

With the continuous growth of the global economy, an increasing concern has emerged among individuals with regard to personal digital health. Smart fiber-based sensors meet people’s demands for wearable devices with the advantages of excellent skin-friendliness and breathability, enabling efficient and prompt monitoring of personal digital health signals in daily life. Furthermore, by integrating machine learning and big data analysis techniques, a closed-loop system can be established for personal digital health, covering data collection, data analysis, as well as medical diagnosis and treatment. Herein, we provide a review of the recent research progress on fiber-based wearable sensors for personal digital health. Firstly, a brief introduction is provided to demonstrate the importance of fiber-based wearable sensors in personal digital health. Then, the monitoring of biophysical signals through fiber-based sensors is described, and they are classified based on different sensing principles in biophysical signal monitoring (resistive, capacitive, piezoelectric, triboelectric, magnetoelastic, and thermoelectric). After that, the fiber-based biochemical signal sensors are described through the classification of monitoring targets (biofluids and respiratory gases). Finally, a summary is presented on the application prospects and the prevailing challenges of fiber-based sensors, aiming to implement their future role in constructing personal digital health networks.

Optical fiber tips with the flat end-facets functionalized take the special advantages of easy fabrication, compactness, and ready-integration among the community of optical fiber devices. Combined with plasmonic structures, the fiber tips draw a significant growth of interest addressing diverse functions. This review aims to present and summarize the plasmonic functionality of optical fiber tips with the current state of the art. Firstly, the mechanisms of plasmonic phenomena are introduced in order to illustrate the tip-compatible plasmonic nanostructures. Then, the strategies of plasmonic functionalities on fiber tips are analyzed and compared. Moreover, the classical applications of plasmonic fiber tips are reviewed. Finally, the challenges and prospects for future opportunities are discussed. Full article
