Abstract
A fiber optic star-coupler with a biconical mixing element and method for inexpensively manufacturing the same are disclosed. The fiber optic star-coupler includes an input fiber optic bundle, an output fiber optic bundle and a biconical mixing element. Each of the bundles comprises a plurality of individual optical fibers. The biconical mixing element includes tapered regions and a central mixing zone to promote uniform mixing and equal distribution of optical energy among all of the optical fibers in the output fiber optic bundle. The biconical mixing element is provided with connectors at each of its two ends for coupling to other connectors, adaptors, and fiber optic bundles. Alternatively, the biconical mixing element may be formed by injection molding techniques. The optical fibers may be constructed from plastic or silica.
