Claim:
1. A photonic waveguide structure comprising: a tapered photonic waveguide structure within a photonic substrate, the tapered photonic waveguide structure having a tapered region that progressively tapers in width along a longitudinal length of the tapered photonic waveguide structure; and an optical fiber waveguide having a core region and a cladding region, a portion of the core region partially exposed by removing a portion of the cladding region, an outer surface of the portion of the core region that is partially exposed substantially coupled to the tapered photonic waveguide structure, wherein an optical signal propagating along the tapered photonic waveguide structure is coupled from the tapered region of the tapered photonic waveguide structure to the core region of the optical fiber waveguide via the core region that is partially exposed, and wherein the tapered region of the tapered photonic waveguide structure and the core region of the optical fiber waveguide that is partially exposed comprise an orientation that is substantially parallel.
