A microstructured optical fiber is described. The microstructured optical fiber comprises an inner region and an outer region. The inner region includes an inner material and a plurality of holes formed in the inner material. The outer region surrounds the inner region, and includes an outer material. The softening point temperature of the inner material is greater than the softening point temperature of the outer material by at least about 50° C. Microstructured optical fiber preforms and methods for making the microstructured optical fibers are also described. The microstructured optical fiber may be made to have substantially undistorted holes in the inner region.
