Abstract

Three asymmetric multi-core fibers namely 3-linear-core-array fiber, 5-linear-core-array fiber and 5-circular-core-array fiber were designed. The supermode characteristics were investigated using a finite element method (FEM) with perfect matched layer (PML) boundaries. The profiles of supermodes supported by these multi-core fibers were presented. The dispersion characteristics of these multi-core fibers had been analyzed. The numerical results show that the peak value group velocity dispersion of the 5-circular-core-array fiber can reach -2.4×10⁵ps/nm·km, and the GVD bandwidth is up to 25nm(1535-1560nm), covering almost the whole C-wavelength band. It can compensate for more than 13000 times its own length that of the ordinary SMF.
