title: Modal-insensitive biconical-taper couplers.
abstract: A method for fabricating optical-fiber fused biconical-taper couplers that have coupling ratios insensitive to the modal distribution of light in the input fiber arms is demonstrated. Comparison measurements of the performance of these couplers and those made by the previous technique are presented and discussed.
