We present a new approach for the development of all-solid microstructured fiber with flat all-normal dispersion in the broadband range of 1550-2500 nm. The use of two soft glasses gives additional degrees of freedom in the design of microstructured fibers. As a result, we have designed and developed a fiber optimized for supercontinuum generation with 1550 nm pulsed lasers in the all-normal dispersion regime within an infrared range, beyond the fused silica glass limit. The measurement of the chromatic dispersion of the manufactured fibers was performed with a white light interferometric method in the spectral range 900-1650 nm. We demonstrate very good agreement between the full vector finite element simulations and the measurement results.
