Patent ID: 7474816

Claim:
An apparatus, comprising: a bottom cladding layer; a photopolymer material formed on the bottom cladding layer, the photopolymer material being patterned to form a waveguide on the bottom cladding layer and having a first height with an integrated optical lens formed on the bottom cladding layer and having a second height, wherein the second height is greater than the first height; wherein the optical lens has a directionally collimating lens curve that has an outline that is substantially defined within at least a plane that is coplanar with the top surface of the bottom cladding layer, wherein the light rays transmitted from the waveguide are collimated such that substantially all of the light rays emitted through the directionally collimating lens curve are parallel to each other and travel in a single direction; and a top cladding layer formed on at least the waveguide.
