Abstract
An optical waveguide structure includes an air-via region that receives an optical signal from an optical source. A photonic crystal cladding region is formed on the surface of the air-via region. The photonic crystal cladding region confines the optical signal within the air-via region and propagates the optical signal along the axial direction while ensuring near complete transmission of the optical signal.
Claims27
An optical waveguide structure comprising:
- an air-via region that receives an optical signal from an optical source;
- a plurality of first photonic crystal cladding regions that are formed on the surface of said air-via region, wherein said photonic crystal cladding regions confines the optical signal within said air-via region and propagates the optical signal along the axial direction while ensuring near complete transmission of said optical signal;
- and
- a second photonic cladding region being positioned orthogonally to said first photonic crystal cladding regions providing endpoint transmission into an optical fiber structure.
