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.
