In this paper, we have numerically simulated a highly nonlinear multi-material chalcogenide photonic crystal fiber in order to investigate both the linear and the nonlinear parameters for generating a supercontinuum. The photonic crystal fiber is designed with borosilicate and As2S3 glass, where borosilicate is doped in a spiral shape in the cladding region of the fiber. The designed fiber was carefully anlaysed for the parameters, effective refractive index, effective mode area, dispersion and nonlinearity coefficient. The estimated parameters are found satisfactory and suitable for further simulation and investigation of the design for broadband supercontinuum generation.
