1. 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 on a surface of the waveguide substrate,
a second wedge on a surface of the first wedge, and
a third wedge on a surface of the second wedge, wherein the third wedge has an input face configured to receive the light, the input face being 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.
