    Abstract: Disclosed herein is a fiber optic-to-waveguide coupling assembly with an overlap for edge coupling. The fiber optic-to-waveguide coupling assembly includes a first coupler having a substrate and at least one data fiber, and an interposer with at least one waveguide. A first coupler overlap portion of the substrate is positionable proximate a first interposer overlap portion of the interposer to form a first overlap therebetween to align the at least one data fiber with the at least one waveguide. The substrate and the interposer may each include complementary alignment features to further align the at least one data fiber and the at least one waveguide. The fiber optic-to-waveguide coupling assembly provides simple and accurate alignment with simplified manufacture and assembly.

    Abstract: A fiber to waveguide coupler is provided that includes an optical fiber having a core and a cladding. The cladding includes an inner cladding and an outer cladding with a polymer. At least one of the core and inner cladding defines a substantially flat surface parallel with an axis of the optical fiber. The optical fiber defines a stripped portion substantially free of outer cladding configured to expose the at least one substantially flat surface of the core or inner cladding. A waveguide is configured to be evanescently coupled with the exposed at least one substantially flat surface of the core or inner cladding.
