Patent ID: 7366380

Claim:
An apparatus comprising: a plurality of optical waveguides disposed on a first substrate, where the first substrate has at least three surfaces: a first surface, a planar base and a planar angled reflective surface, and the first surface is at an angle with respect to the base, and the angled reflective surface is at an acute angle with respect to the base, and each of the plurality of optical waveguides: is substantially parallel and substantially adjacent to the base of the first substrate and has first and second optical ports, and the first optical port is located at the first surface, and the second optical port is located at the angled reflective surface; and a second substrate and a plurality of optical structures disposed on the second substrate, where the base of the first substrate is positioned on top of, substantially parallel, and substantially adjacent to the top surface of the second substrate, and at least one of the plurality of optical structures on the second substrate is substantially optically aligned with the second optical port of at least one of the plurality of optical waveguides on the first substrate.
