Abstract(in English) | We reveal the relationship between group index and group delay spread (GDS) in coupled multicore fibers for space division multiplexing (SDM) transmission under macrobending condition, and propose a structure reducing GDS further. First, we explain GDS analysis method under macrobending condition. Next, we discuss the physical reason of discontinuous behavior of GDS in terms of core-to-core distance and demonstrate that it can be explained from the relationship between group index and GDS. Finally, a novel fiber structure with small GDS and high core density is proposed to reduce GDS at the discontinuous point. |
