DOI: 10.1016/j.yofte.2016.09.017
Abstract: Abstract Few-mode multicore fibers (FM-MCFs) that enable dense space-division multiplexing (DSDM) have the potential to drastically improve the fiber capacity. In designing the FM-MCFs, several issues that originate from multicore fibers and few-mode fibers must… read more here.

DOI: 10.1016/j.yofte.2019.02.015
Abstract: We propose improved design of heterogeneous trench-assisted multicore fibers (MCFs) for wideband space division multiplexing (SDM) optical transmission. By adopting different parameters for heterogeneous cores, the trade-off among the effective area (Aeff ), cut-off wavelength… read more here.

DOI: 10.1109/jlt.2017.2754218
Abstract: A time-varying phase shift associated with each phase matching point of homogeneous weakly coupled multicore fibers is proposed to describe the stochastic time evolution of the intercore crosstalk (ICXT) observed experimentally. This model for the… read more here.

DOI: 10.1109/jlt.2020.2980955
Abstract: We assess the potential applicability and performance of multicore fibers (MCFs) against conventional single-core fibers (SCFs) in submarine transmission systems. In particular, we assume 4-core MCFs with nominally uncoupled cores and separate amplification of each… read more here.

DOI: 10.1364/oe.480209
Abstract: We quantitatively discussed the effect of core-dependent loss (CDL) on the crosstalk (XT) of multicore fibers (MCFs). In practical ranges of XT and CDL, CDL has no significant effect on power coupling coefficients and XT… read more here.
