Abstract

It is provided a circuit assembly, comprising at least one electronic circuit; at least one optical waveguide, wherein the core and the cladding of the optical waveguide are formed of an amorphous material; at least one carrier on which the optical waveguide is arranged; and at least one electro-optically active material layer electrically connected to the electronic circuit. The at least one electro-optically active material layer at least partially extends in the optical waveguide and the electrical connection between the electronic circuit and the at least one electro-optically active material layer is produced in that at least one electrical contact extends from the electronic circuit through at least one section of the cladding of the optical waveguide to the at least one electro-optically active material layer or is connected to a section of the electro-optically active material layer, which protrudes from the cladding of the optical waveguide.
