Patent ID: 7672560

Claim:
A coupling device for coupling light with an optical waveguide, the coupling device comprising: a mirror formed within an optical waveguide, the mirror comprising a first material, a first reflective surface, and a second reflective surface, wherein the first reflective surface is substantially opposite to the second reflective surface, wherein the first material is light conducting and has a first refractive index, wherein the first reflective surface reflects and transmits light, wherein the second reflective surface reflects and transmits light, and wherein the mirror has an optical axis line; and a reflector comprising a second material, wherein the reflector is approximately parallel to the optical axis line, wherein a line perpendicular to the optical axis line will intersect at least one of the first and second reflective surfaces and intersect the reflector; wherein the first reflective surface, the second reflective surface, and the reflector are positioned such that light is collected and propagated out of the coupling device in approximately one direction.
