Abstract: Structures including an edge coupler, and methods of fabricating a structure that includes an edge coupler. The structure (10) includes an edge coupler having a waveguide core (12) with an end surface (14) and a longitudinal axis (18). The end surface (14) defines a plane tilted in a first direction at a first acute angle relative to the longitudinal axis (18) and tilted in a second direction at a second acute angle relative to the longitudinal axis (18). The second direction differs from the first direction.
