Tapered photonic waveguide to optical fiber proximity coupler
First Claim
1. A method of forming a photonic waveguide coupling device from a fiber optic ferrule device having a single row of substantially parallel fiber holes for receiving a plurality of optical fibers, the method comprising:
- forming a fiber mounting block by removing a top portion of the fiber optic ferrule device, the removed top portion converting the single row of substantially parallel fiber holes into a single row of substantially parallel channels;
placing the plurality of optical fibers having end facets in the single row of substantially parallel channels, the end facets being substantially flush with end portions of the single row of substantially parallel channels; and
polishing the plurality of optical fibers to partially expose core regions of the plurality of optical fibers and generating a downward sloping angle along the length of the core regions towards the end facets,wherein the partially exposed core regions of the plurality of optical fibers having the downward sloping angle along the length of the core regions towards the end facets provide optical coupling with a plurality of tapered photonic waveguide structures in an integrated circuit.

Abstract
A photonic waveguide structure may include a tapered photonic waveguide structure within a photonic substrate, such that the tapered photonic waveguide structure has a tapered region that progressively tapers in width along a longitudinal length of the tapered photonic waveguide structure. The photonic waveguide structure also includes an optical fiber waveguide having a core region and a cladding region, whereby a portion of the core region is partially exposed by removing a portion of the cladding region. An outer surface of the portion of the core region that is partially exposed is substantially coupled to the tapered photonic waveguide structure. 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.
