Spatial-division-multiplexed optical fiber: devices and sensing applications
1  Huazhong University of Sci & Tech


Together with the progress in telecommunications, the high quality multicore fiber (MCF) and few-mode fiber (MCF) are developed with reliable spatial-division multiplexer/demultiplexers for innovative fiber devices and sensing applications. We will review our recent progress in the spatial-division-multiplexed (SDM) fiber devices and their applications in discrete and distributed fiber sensing, such as integrated parallel LPG, MZI, MI and the distributed curvature and 3D shape sensing. The simultaneous multi-parameter measurement using discrete/distributed technologies are also introduced.

Keywords: spatial-division multiplexing; multi-core fiber; few-mode fiber
