Abstract
A monolithic optocoupler has a semi-insulating substrate and two opto-components (A, B) arranged thereon, between which signals and/or power can be transmitted through optical radiation. In order to suppress interference transferred capacitively and/or resistively between the two components, screening means are arranged on the substrate between the two components. The screening member is produced using the same type of integrated-circuit technique as for the opto-components, and preferably in the same manufacturing step as these components. The screening member is suitably provided with connection means for its grounding.
