A fiber optic waveguide is disclosed. The fiber optic waveguide includes a core region, and a moat region surrounding the core region. A cladding region surrounds the moat region and the core region. The cladding region includes a lattice of column structures disposed within a solid background matrix. A diameter of the core region is sized for making contact with the moat region for creating an extended core region at longer wavelengths. The core region, the moat region, and the cladding region function to produce unique dispersion compensating properties, which include negative dispersion and positive dispersion. The core region may be formed from a high index material and the moat region may be formed from a material having a refractive index lower than the refractive index of the core region. The cladding region is formed from a material having a refractive index which is higher than the index of the moat region and lower than the refractive index of core region.
