Few-Mode Fiber refers to an optical fiber that is designed to support multiple guided modes. In traditional single-mode fibers, only one mode of light propagation is supported. In few-mode fibers, on the other hand, a small number of modes can be guided. These modes correspond to different spatial patterns of light within the fiber core. Few-mode fibers have potential applications in increasing data transmission capacity in optical communication systems.


Distributed Optical Fiber Sensing Using Specialty Optical Fibers

Distributed fiber optic sensing systems use long section of optical fiber as the sensing media. Therefore, the fiber characteristics determines the sensing capability and performance. In this presentation, various types of specialty optical fibers and their sensing applications will be introduced and discussed.
