Abstract
Embodiments of the present invention generally relate to laser combiners, and more specifically, to all-fiber devices that combine optical laser power from multiple separate sources such as lasers or amplifiers. In one embodiment, a method of manufacturing a combiner device comprises: positioning an plurality of fibers into a bundle of fibers; drawing the bundle of fibers to create a tapered section, the tapered section having a first outer diameter at an input end, a second outer diameter at an output end, and a taper ratio of at least three; wherein at least one of the fibers of the bundle of fibers comprises an optical waveguide configured for propagating an optical mode from the input end to the output end, and wherein a mode field diameter of the optical mode at the input end is substantially the same as the mode field diameter at the output end.
