Abstract :
The coupling characteristics of two-core multimode fiber coupler are studied. A theoretical model solution of the wave equation for a multimode optical fiber for computing its propagation is analyzed. In addition, the dependence of the coupling efficiency on the wavelength, the separation between the two cores and the refractive index is studied. The effect of the length of the coupling region along the two-multimode core fiber coupler and the refractive index on the coupling characteristics is also investigated. The obtained results are agree with the physical performance of the multimode optical fiber coupler
