چکیده انگلیسی
12-Core 5-LP mode homogeneous multicore fibers have been proposed for analysis of inter-core crosstalk and dispersion, with four different lattice structures (circular, 2-ring, square lattice, and triangular lattice) having cladding diameter of 200â¯Âµm and a fixed cladding thickness of 35â¯Âµm. The core-to-core crosstalk impact has been studied numerically with respect to bending radius, core pitch, transmission distance, wavelength, and core diameter for all 5-LP modes. In anticipation of further reduction in crosstalk levels, the trench-assisted cores have been incorporated for all respective designs. Ultra-low crosstalk (-138â¯dB/100â¯km) has been achieved through the triangular lattice arrangement, with trench depth Î2â¯=â¯â1.40% for fundamental (LP01) mode. It has been noted that the impact of mode polarization on crosstalk behavior is minor, with difference in crosstalk levels between two polarized spatial modes asâ¯â¤0.2â¯dB. Moreover, the optimized cladding diameter has been obtained for all 5-LP modes for a target value of crosstalk of â50â¯dB/100â¯km, with all the core arrangements. The dispersion characteristic has also been analyzed with respect to wavelength, which is nearly 2.5â¯ps/nm km at operating wavelength 1550â¯nm. The relative core multiplicity factor (RCMF) for the proposed design is obtained as 64.
