الملخص الانجليزي
Coupling characteristics of two-core photonic crystal fiber are analyzed using COMSOL MULTIPHYSICS software that is depended on the finite element method. The effective mode indexes and the electric field distributions, coupling length for different geometrical designs are evaluated. The results show the coupling length dependence the wavelengths to realize significantly short coupling lengths of two-core photonic crystal fiber in um at the telecom wavelength 1.55 um and 1.31 um compared with the traditional fiber coupler. The geometrical parameters of the PCF play an important role in the dependence of the mode characteristics between cores of PCF coupler, such as the hole diameter, hole pitch, air-filling fraction and, core separation. Increasing the core separation leads to a drastic reduction in the coupling strength between the cores of photonic crystal fiber or may lead to suppression of the coupling between the cores of photonic crystal fiber. Our proposed is an excellent device for coupler and power splitter, multiplex and de-multiplex applications.
