A design of technologically feasible hole-assisted silica fibers with all-normal dispersion was proposed and optimized for maximum dispersion located, respectively, at 1.55 and 1.97 μm. Such fibers allow for efficient supercontinuum generation using erbium- or thulium-doped fs fiber laser as a pump. Nonlinear simulations accounting for fiber loss were performed to find optimum pumping conditions. Our results point to the possibility of coherent supercontinuum generation in silica fibers with a long-wavelength limit reaching midinfrared.
