Abstract:	Analytical expression is derived for the mode-coupling coefficient between non-identical step-index (SI) cores, which enables a quick estimate of the crosstalk in the heterogeneous SI multi-core fibers (Hetero-SI-MCFs). The analytical results are in good agreement with the results obtained by numerical simulations by finite-element method (FEM). Using the derived analytical expression, the feasibility of Hetero-SI-MCF design within standard 125-mu m cladding diameter is discussed. The designed MCFs have potential applications in space division multiplexing (SDM) systems.
