Title (DE) MULTIMODE-INTERFERENZKOPPLER UND VERFAHREN ZU SEINER KONSTRUKTIVEN AUSGESTALTUNG
(EN) MULTIMODE INTERFERENCE COUPLER AND METHOD FOR THE STRUCTURAL CONFIGURATION THEREOF
(FR) COUPLEUR D'INTERFÉRENCE MULTIMODE ET PROCÉDÉ PERMETTANT SA CONFIGURATION CONSTRUCTIVE
Abstract: front page image
(DE)Die Erfindung betrifft einen Multimode-Interf erenzkoppler (MMI) mit mindestens einem Zuführungswellenleiter und mindestens einem Ausgangswellenleiter, wobei der MMI entlang seiner Längserstreckung in Richtung des Zuführungswellenleiters zumindest einen Längsabschnitt aufweist, in welchem der Brechungsindex in einer Richtung, welche im Wesentlichen rechtwinklig zur Richtung des Zuführungswellenleiters verläuft, einen örtlich oszillierenden Verlauf aufweist. Weiterhin betrifft die Erfindung ein Verfahren zur konstruktiven Ausgestaltung eines Multimode-Interf erenzkopplers.
(EN)The invention relates to a multimode interference coupler (MMI) comprising at least one supply waveguide and at least one output waveguide, wherein the MMI has along its longitudinal extent in the direction of the supply waveguide at least one longitudinal section in which the refractive index has a locally oscillating profile in a direction running substantially at right angles to the direction of the supply waveguide. The invention furthermore relates to a method for the structural configuration of a multimode interference coupler.
(FR)L'invention concerne un coupleur d'interférence multimode (MMI) comprenant au moins un guide d'ondes d'entrée et au moins un guide d'ondes de sortie, caractérisé en ce que le MMI comprend, le long de son extension longitidinale en direction du guide d'ondes d'entrée, au moins une section longitudinale dans laquelle l'indice de réfraction présente, dans une direction qui est sensiblement perpendiculaire à la direction du guide d'ondes d'entrée, un profil à oscillations locales. L'invention concerne en outre un procédé permettant la configuration constructive d'un coupleur d'interférence multimode.
