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.

An optical waveguide structure comprising:
- an air-via region that receives an optical signal from an optical source;
- and
- a photonic crystal cladding region that is formed on the surface of said air-via region, wherein said photonic crystal cladding region 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.
A monolithical optical structure comprising:
- an air-via region that receives an optical signal from an optical source;
- and
- a photonic crystal cladding region that is formed on the surface of said air-via region, wherein said photonic crystal cladding region 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.
A method of forming a waveguide structure comprising:
- providing an air-via region that receives an optical signal from an optical source;
- and
- forming a photonic crystal cladding region on the surface of said air-via region, wherein said photonic crystal cladding region 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.
