Abstract

An arrangement is composed of at least two waveguides, which are coaxially optically coupled to one another integrated on the surface of the substrate with different degrees of wave guidance. The axis of the more weakly-guiding waveguide is straight and the axis of the more strongly-guiding waveguide comprises a curved section.
