Abstract:
1. An optical combiner, including: a plurality of first refractive elements adapted to receive a corresponding plurality of optical input beams, each of the plurality of first refractive elements having a first refractive index; and a second refractive element disposed substantially parallel to the plurality of first refractive elements and adapted to receive a refracted input beam from each of the plurality of first refractive elements, the second refractive element having a second refractive index greater than the first refractive index and including a first internal reflective surface, wherein the first internal reflective surface is adapted to provide internal reflection of the refracted input beams toward an exit; wherein the plurality of first refractive elements and the second refractive element are configured to combine the plurality of optical input beams into an optical output beam at the exit.
