1. A system comprising:
an optical waveguide structure of an optical integrated circuit, the optical waveguide structure comprising a substrate and a waveguide core forming an optical waveguide path disposed on the substrate, wherein the waveguide core comprises a nanotaper; and an optical coupler disposed over the waveguide core, the optical coupler comprising a fiber optic structure that comprises a core portion and a cladding portion, wherein an outer surface of the fiber optic structure comprises: a first outer surface portion beveled at a predetermined angle relative to a longitudinal axis of the fiber optic structure, the beveled first outer surface portion being a substantially flat surface comprising the core portion and the cladding portion, wherein the substantially flat beveled first surface portion faces the waveguide core to optically couple the optical coupler with the waveguide core, and wherein the core portion of the beveled first outer surface portion faces and is aligned with the nanotaper; and a second outer surface portion comprising the core portion and the cladding portion, wherein the core portion of the fiber optic structure extends a first length over the beveled first outer surface portion according to the predetermined angle, and wherein the first length is substantially equal to a length of the nanotaper. |
