Abstract:
A fiber optic waveguide comprising:a core region; anda cladding region surrounding the core region, the cladding region including an inner cladding region and an outer cladding region, the inner cladding region is a solid material having a lattice of annular ring structures therein; such that the core region functions as a defect in the lattice of ring structures for guiding light within the fiber optic waveguide;each annular ring structure is formed by an annular ring surrounding an inner core, where the annular ring is a solid material having a refractive index different than the refractive index of the solid material forming the remainder of the inner cladding region and the inner core is a material having a refractive index which is lower than the refractive index of the solid material forming the annular ring.
