A fiber optic waveguide is provided. The fiber optic waveguide includes a core region, and a cladding region surrounding the core region. The cladding region includes an inner cladding region and an outer cladding region. The inner cladding region has a lattice of ring structures. The core region is formed from a high index material and the cladding region is formed from materials producing an effective refractive index lower than the refractive index of the core region.
