Dear Colleagues,

We are pleased to invite you to submit an article to a new Special Issue of Photonics called “Advances in Fiber Optics”. Optical fibers have experienced much success and have been applied in our daily life, in different industries, and in academia. They have continued to be rapidly developed since Dr. Kao and his collaborators reported on the possibility of optical fibers in telecommunication in 1966. Currently, areas such as new mechanisms and fabrication techniques, nanophotonic effects, and edge-cutting applications of optical fibers are attracting a large amount of attention. Notably, we can recognize the trend in developing fiber-optic components with miniaturized sizes and complex performances by either engineering the geometric features of optical fibers or integrating functional elements (2D materials, metasurfaces, and responsive media) into optical fibers. Additionally, there is increasing interest in novel active optical fiber devices and the nanophotonic capabilities of fiber optics.

This Special Issue welcomes works within all linear and nonlinear aspects of fiber optics, from fundamental studies to emerging applications. Submissions related to functional fibers with integrated nanostructures and new mechanisms and approaches of micro-structured fibers are strongly encouraged. We look forward to receiving your contributions.
