  • HOLLOW CORE FIBER POWER COMBINER AND DIVIDER
    Publication number: 20120027368
    Abstract: A method for manufacturing a hollow core fiber power combiner or divider is provided. The method includes forming a hollow core fiber bundle by assembling a plurality of small core diameter hollow core fibers inside a large diameter inner capillary. The method further includes inserting a support structure inside each of the plurality of small core diameter hollow core fibers and collapsing the large diameter inner capillary on the plurality of small core diameter hollow core fibers having the supported structure inserted to form a fused small core fiber bundle. The method further includes combining the fused small core fiber bundle with a large core diameter hollow core fiber. The structure of the hollow core fiber power combiner and divider is also provided.
