In this paper, tetra-core and dual-core photonic crystal fiber (PCF) with hybrid cladding have been suggested for coarse wavelength division multiplexing (CWDM) systems. The designing parameters have reformed to optimize the optical properties of the proposed structure. Finite element method (FEM) is utilized to perform the numerical analysis of the proposed S-PCF. Also, The proposed tetra-core PCF exhibits a negative dispersion about −631 ps/nm.km and high nonlinearity of 8.268×1013 W−1km−1 at a wavelength of 1550 nm. On the another side, the dual-core PCF exhibits a negative dispersion about −6.801 ps/nm.km and high nonlinearity of 8.268×1013 W−1km−1 at a wavelength of 1550 nm. Besides Effective area and field distribution are also described briefly.read more
