Design analysis of low crosstalk bend insensitive wideband heterogeneous high density multicore fiber with standard cladding diameter

In this paper impact of different heterogeneous core configurations have been analyzed to obtain low values of crosstalk and peak bending radius over the S + C + L wavelength band in multicore fiber with standard cladding diameter. Heterogeneous multicore fibers having 6-core, 8-core, 10-core, and 12-core within standard cladding diameter have been designed and simulated. The design optimization of the heterogeneous core configuration, results in the suppression of crosstalk value below −41.25 dB/km over the S + C + L wavelength band and peak bending radius value 10 mm of the 12-core MCF . The designed standard cladding diameter based high density heterogeneous MCF s have potential application in wideband space division multiplexing ( WB-SDM ) transmission systems.
