Abstract

Abstract Translated from German Es wird eine Lichtwellenleiterverzweigung nach dem Strahlteilerprinzip beschrieben, bei welcher zur Verminderung von Polarisationseffekten der zwischen fluchtenden Lichtwellenleitern (1,1') angeordnete Strahlteilerspiegel (3) in einem Winkel (B) zur gemeinsamen Achse der fluchtenden Lichtwellenleiter hin geneigt ist, der größer als 45° ist. An optical waveguide branch according to the beam splitter principle is described, in which, in order to reduce polarization effects, the beam splitter mirror (3) arranged between aligned optical waveguides (1, 1 ') is inclined at an angle (B) to the common axis of the aligned optical waveguides that is greater than 45 ° is.
