Patent ID: 7155106

Claim:
A wave guide comprising: a tubular body with a reflective inner surface defining a hollow interior, the tubular body having a proximal end, a distal end, and a cross section defining a polygon, the proximal end adapted to optically couple to an electromagnetic wave with an initial distribution, the reflective interior surface of the hollow tubular body adapted to reflect a portion of the initial distribution toward a center of the tube and allow the wave to travel through the hollow interior of the body from the proximal end to the distal end, and the distal end adapted to optically couple the wave therefrom, the wave to substantially have a uniform intensity distribution near the distal end; and further comprising a coupler mechanically coupled to the body and adapted to mechanically couple to a source optical fiber generally adjacent the proximal end to thereby optically couple the source optical fiber to the proximal end, the coupler further adapted to mechanically couple to a plurality of optical fibers generally adjacent the distal end to thereby optically couple the plurality of fibers to the distal end.
