Abstract
Single mode fiber beam combiners are formed by extending single mode fibers through a glass ferrule, and tapering and fusing the fibers and the ferrule. Tapers can be selected so that optical power input to each of the single mode fibers remains partially guided by the single mode fiber cladding, or is guided by the multimode fiber formed by the glass ferrule and the fused fiber claddings. Such combiners can include double clad fibers or actively doped fibers for use in lasers or amplifiers.
