Abstract
The invention relates to an assembly for optical coupling and for mode-selective separation or overlaying of optical fields, to the use thereof and to a method for producing a waveguide-based optical coupling element () which is designed for mode-selective separation or overlaying of optical fields at a further optical coupling point () of an optical component (). The assembly comprises at least one waveguide-based optical coupling element () having at least three optical coupling points (), and at least one optical component () having at least one further optical coupling point (), wherein at least one of the optical coupling points) is optically connected to the at least one further optical coupling point (), and wherein the waveguide-based optical coupling element () is designed to transmit light highly efficiently and bidirectionally between eigenmodes () associated with the first optical coupling point () and the second optical coupling point (), and between eigenmodes () associated with the first optical coupling point () and the third optical coupling point ().
