Abstract
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.
Claims19
A fiber optic waveguide comprising:
- a core region;
- and
- a 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.
