Abstract:
An optical device comprises a fiber having a cladding and a core, and a target PIC waveguide having a cladding and a core. The cladding on one side of the input fiber is removed at the end of the fiber and a flat surface is created along the fiber core, close to the core, exposing the fiber core. A flat-bottomed channel having an in-plane angle with respect to the symmetric axis of the PIC waveguide is fabricated on the top layer of the PIC waveguide in the coupling area, exposing the upper surface of the tapered planar waveguide. The flat surface of the fiber and the top surface of the waveguide is contacting, so the core of the fiber is intersected at an angle with respect to the symmetric axis of the target waveguide and close together at the intersection as an interacting region to define a hybrid waveguide.

Claim (Index 17):
An optical device compromising:\n an input fiber configured to provide a light input, the input fiber having a cladding and a core, the cladding on one side of the input fiber being removed at an end of the input fiber thereby creating a flat surface along the input fiber for a predetermined distance, the flat surface configured to be close to the core of the fiber such that the fiber core is exposed; a target photonic integrated circuit (PIC) waveguide configured to receive the light input, the target PIC waveguide being planer and having a top cladding layer and a core; a flat-bottomed channel fabricated on the top cladding layer of the target PIC waveguide in a coupling area, such that the upper surface of the target PIC waveguide is exposed, the flat-bottomed channel having an in-plane angle with respect to a symmetric axis of the PIC waveguide; the flat surface of the input fiber configured to contact the top surface of the target PIC waveguide such that the core of the input fiber and the core of the target PIC waveguide are close and in parallel to each other in the coupling area to form a hybrid waveguide; a first transition for coupling of light from the input fiber to the hybrid waveguide; and a second transition for coupling of light from the hybrid waveguide to the target PIC waveguide; the coupling area configured to be between the first transition and the second transition in a lengthwise direction within a plane of the PIC waveguide.
