Abstract

Es wird eine Polymer-Lichtleitfaser beschrieben, die einen Abschnitt aufweist, der einen kreisförmigen Querschnitt aufweist, und einen Abschnitt, der einen nicht kreisförmigen Querschnitt aufweist. Weiterhin werden optische Bauteile beschrieben, die eine solche Lichtleitfaser enthalten, sowie ein Verfahren zur Herstellung einer solchen Lichtleitfaser. Gemäß einer Ausführungsform der Erfindung wird vorgesehen, daß ein Splitter mit einer Eingangsfaser und zwei Ausgangsfasern gebildet wird, wobei die beiden Ausgangsfasern jeweils einen halbringförmigen Querschnitt haben. Die beiden halbringförmigen Lichtleitfasern umgeben die Eingangsfaser.
