Multicore photonic crystal fibers (MPCF) with identical and non-identical cores
are analyzed numerically using Comsol Multiphysics software. Investing
coupling between cores limiting by parameters, such as the slight change in
central core diameter; the separation distance between cores and the
wavelength were investigated. Controlling these parameters allows predicting
the mode propagation. Moreover, anisotropy in all cores diameters of multicores
photonic crystal fibers, as a result, the change of all core diameters
simultaneously lead to different of coupling behavior, suppresses the coupling
between the core modes by inducing a small mismatch between the modes such
that the core modes to be uncoupled through this change. Then this leads to the
light mode propagate independently of their neighbors and gives rise to the
mode to primarily remain in a certain region of the MPCF array. These
properties suggest that multicore PCFs could be a novel candidate for both
multiplex or de-multiplex.
