Claim 17:
18. An electronic device comprising:
a waveguide having a waveguide substrate and a medium on between the waveguide substrate;
a prism on the waveguide substrate and configured to couple light into the medium through the waveguide substrate, wherein the prism comprises:
a first wedge mounted to a surface of the waveguide substrate, wherein the surface of the first waveguide substrate has a first normal axis, and
a second wedge mounted to a surface of the first wedge, wherein the surface of the first wedge has a second normal axis, the second normal axis is oriented at a first non- zero angle with respect to the first normal axis within a first plane, and the second normal axis is oriented at a second non- zero angle with respect to the first normal axis within a second plane, the first plane being perpendicular to the second plane; and

an optical coupler on the medium and configured to couple, out of the waveguide, the light coupled into the medium by the prism.
