Fiber pump combiner

Abstract:

An optical fiber combiner comprising a coupling device having an input surface area, and you A.sub.in, and an output surface area, A.sub.out, wherein the input surface area A.sub.in is greater than the output surface area A.sub.out, and a plurality of optical fibers each having an input surface and an output surface, wherein the output surfaces of the plurality of optical fibers are coupled to the coupling device, wherein the coupling device combines optical power emitted by the plurality of optical fibers.
