A waveguide assembly includes first and second waveguides. The first waveguide includes silicon, first and second ends, an end member, and a tapered member. The end member extends from the first end. The tapered member extends from the end member to the second end. The second waveguide is optically coupled to and spaced away from the first waveguide. The second waveguide includes silicon nitride, first and second members, and a non-tapered member. The non-tapered member extends from the first member to the second member and in parallel with and opposing the tapered member. An effective refractive index of the non-tapered member matches an effective refractive index of the tapered member at a first plane. The first plane extends through the non-tapered member and the tapered member and perpendicular to a second plane. The second plane extends parallel to a direction of overlap between the first and second waveguides.
