Abstract:
1. A system for fusing first and second optical waveguide sections together, each optical waveguide section having a core surrounded by a cladding, comprising: at least one source laser to provide at least one laser beam; first and second stages to hold the first and second optical waveguides, respectively, wherein at least one of the first and second stages is movable to provide relative motion between the first and second optical waveguides while holding portions of the first and second optical waveguides to be fused within a fusion splice region while aligning their respective cores; and a beam delivery arrangement to deliver at least two laser beams to different locations of the fusion splice region, wherein the at least two laser beams are generated from the at least one laser beam provided by the at least one source; wherein at least one of the stages is capable of holding an optical waveguide having a cross-sectional dimension greater than 400 um.
