Claim 12:
13. An electronic device comprising:
a waveguide having a waveguide substrate and a medium on 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, and
a second wedge mounted to a surface of the first wedge, wherein the surface of the first wedge is curved, the second wedge has an input face configured to receive the light, and the input face is non-parallel with respect to the surface of the waveguide substrate; and
an optical coupler on the medium and configured to couple, out of the waveguide, the light coupled into the medium by the prism.
