We demonstrate all-solid optical fibers combined with fluoride and chalcogenide glasses.They are thermally matched in order to be drawn from a hybrid preform directly.The refraction difference between the two kinds of glass allows more adjustability for dispersion control.The full-vector finite-element method is applied to obtain the effective refraction index, thus the group velocity dispersion.Geometry dimensions of the fiber are slightly tailored to fulfill all normal dispersion profile and the top around 2μm is close to zero dispersion.The properties of the supercontinuum spectrum are studied by solving the Generalized Nonlinear Schrodinger Equation numerically with different pumping conditions.Using a 175W peak power 100fs duration pumping light of 2μm, a broadband spectrum with high coherency ranging from 1250nm to 2750nm can be obtained in this kind of all-solid composite optical fiber.
