Raised Cosine Multicore Fibers For High-Density Space Division Multiplexing (H-DSDM) Systems

Space division multiplexing (SDM) over multicore few mode fibers (MC-FMFs) is considered among the latest technological drive towards high data rates in next generation optical communication systems. In this paper, we propose and design novel (MC-FMFs) that we refer to as raised cosine multicore fibers MC-RCFs and Trenched-raised cosine multicore Fibers (MC-TRCFs). the designed MCFs has seven cores each of which supports seven orthogonal spatial modes with large effective mode area (min A

) and with low differential mode delay (DMD) (max DMD =33 ps\\\\\\\\km). The intercore crosstalk of each designed fiber and their associated relative core multiplicity factor (RCMF) are assessed, discussed and compared with recently reported MCFs. The designed fibers are promising candidates for next generation short and medium haul interconnect dense-SDM systems.
