A fiber optic waveguide (30) is provided. The fiber optic waveguide includes a core region (34), and a cladding region surrounding the core region. The cladding region includes an inner cladding region (32) and an outer cladding region (42). 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.
