Abstract
In an integrated optical circuit with waveguides applied on a substrate, a layer of high conductivity and a layer of lower index of refraction than the waveguides are arranged between the substrate and the waveguide cores. The circuit permits a favorable coupling of opto-electronic components arranged in the substrate with the waveguides and it can be manufactured by well-known methods.
