  • Optoelectronic coupling element with transparent spacer elements
    Patent number: 4851695
    Abstract: An optoelectronic coupling element with a light-emitting semiconductor component (1), in particular a transmitter chip, and a light-receiving semiconductor component (2), in particular a receiver chip, are firmly joined together via an optic coupling medium (3). The construction of this compact coupling element is to require relatively little expense and thus to be cost-effective. To this end the invention provides that the light-emitting semiconductor component (1) and the light-receiving semiconductor component (2) are connected together directly through the coupling medium (3), and that the coupling medium (3) is a transparent adhesive or glass solder compound. The optoelectronic coupling element disclosed is highly suitable for use as an optocoupler for signal transmission.
