Abstract

Abstract Translated from German Damit ein optischer Stern-Koppler für Multimode-Lichtleitfasern, bei dem zwei Bündel von Elementfasern (3) über ein planares Wellenleiter-Mischerelement (2) miteinander verbunden sind, wobei die Dicke des planaren Wellenleiter-Mischerelements (2) etwa gleich dem Elementfaserdurchmesser ist, und wobei der Gesamtdurchmesser der Element- fasern (3) etwa gleich dem Kerndurchmesser der mit dem Stern-Koppler zu verbindenden System-Fasern (4) ist, geringe Verluste und gute Leistungsgleichverteilung auch bei Gradientenprofil-System-Fasern (4) aufweist, werden als Elementfasern (3) entweder Gradientenfasern oder Stufenprofilfasern mit möglichst dünnen Mänteln verwendet. So that an optical star coupler for multimode optical fibers, in which two bundles of element fibers (3) are connected to one another via a planar waveguide mixer element (2), the thickness of the planar waveguide mixer element (2) being approximately equal to the element fiber diameter, and wherein the total diameter of the element fibers (3) is approximately equal to the core diameter of the system fibers (4) to be connected to the star coupler, has low losses and good power distribution even with gradient profile system fibers (4) are considered as Element fibers (3) either gradient fibers or step profile fibers with the thinnest possible sheaths.
