ABSTRACT:
An optical fiber delivery system having a semiconductor light source that produces an optical output. A plurality of first optical fibers each has an input end and an output end. The input ends are optically coupled to the semiconductor light source to receive the optical output, and the output ends are bundled together. An optical connector positions the input end of a second fiber, relative to the first fiber output ends, to receive the optical output from the first fibers. Either each of the first fibers, or the second fiber, have a tapered segment with a core and a cladding tapered down smoothly in diameter to reduce the spot size of optical output.
