AbstractThe multicore fibre (MCF) is an effective and auspicious technology to overawe the limitation of the single-mode fibre. One of the important applications of MCF is power over fibre. In this paper, we have been designed eight different hexagonal structures by using 6, 7, 8, 9, 10, 11, 12 and 13 cores MCF. Those designs are categorized as even core multicore fibre (ECMCF) for 6, 8, 10 and 12 cores and odd core multicore fibre (OCMCF) for 7, 9, 11 and 13 number of cores. We also studied the impact analysis of odd or even number of the cores. The proposed designs having 140 µm diameter, large effective area of 1256 µ2m and two pitches d1=20 µm and d2=10 µm. The comparative analysis has been done by core multiplicity factor, electric field, coupled power, cross overpower parameter calculated for 10,000 samples. The hexagonal core shape MCF shows better performance if the number of the core in even number.
