ABSTRACT:
A coupling device for coupling two waveguides having different cross sections, for example a layer conductor or laser element to a strip conductor, characterized by a telescopic system, which narrows the beam cross section of the larger of these two waveguides and directs it onto a large cross-sectional end of a tapering waveguide, which tapers down to the cross section of the other waveguide or conductor. The telescopic system can be composed of one conical gradient lens, two coaxial gradient lenses, or a gradient lens coaxially arranged with a conical gradient lens. The tapering waveguide preferably is integral with the strip waveguide or conductor and is of the same type.
