Abstract
An optical system including a plurality of fibers each providing a fiber beam and at least one tapered fiber bundle. The tapered fiber bundle includes a plurality of input end fibers, a plurality of output end fibers and a center bundle portion, where each input end fiber is coupled to a separate one of the fibers, and where the bundle portion combines all of the fiber beams received by the input end fibers into a single combined beam and each output end fiber is capable of receiving the combined beam separately from the other output end fibers. The optical system also includes a plurality of optical output channels where each optical output channel is coupled to a separate one of the output end fibers.
