FU Song-nian, WANG Yan-lin, LAN Tian-ye, et al. The Application of Transmission and Sensing based on MC-FMF(Invited)[J]. 2017,(6):12-20. DOI: 10.13756/j.gtxyj.2017.06.002.
Spatial Division Multiplexing(SDM)using either few-mode or multi-core fiber is regarded as one of potential solutions to solve future capacity crunch of traditional Standard Single Mode Fiber(SSMF).Meanwhile
thanks to the successful development of some critical SDM device
SDM technique can also be applied for distributed fiber optical sensor with multiple parameters simultaneous monitoring
in order to solve the cross sensitivity of traditional SSMF-based fiber sensor with single parameter monitoring.We review recent progress of few-mode fibers
multi-core fibers
multi-core few-mode fibers
in term of design
fabrication and characterization.Moreover
recent progress of those specialty fibers for SDM transmission and fiber sensor applications are presented.Finally
the prospect of the transmission and sensing applications using either few-mode or multi-core fiber are summarized.
