Abstract
A waveguide includes a cladding region that has a refractive index that is substantially uniform and surrounds a wave-guiding region that has an average index that is close to the index of the cladding. The wave-guiding region also contains a thin ring or series of rings that have an index or indices that differ significantly from the index of the cladding. The ring or rings enable the structure to guide light.
Claims22
An optical fiber, comprising;
- a core comprising a first index of refraction (N);
- a concentric ring embedded within said core, wherein said concentric ring comprises a second N;
- and
- a cladding surrounding said core, wherein said cladding comprises a third N.
1 more element
A fiber optic, comprising:
- a core comprising at least one embedded region, wherein said comprises a first region comprising a first index of refraction, wherein said at least one embedded region comprises a second index of refraction;
- and
- a cladding region surrounding said wave-guiding region, wherein said cladding region comprises a third index of refraction, wherein an average of said first index of refraction and said second index of refraction is about equal to said third index of refraction.
