Abstract
The optic coupling system links a fiber-optics waveguide with two optoelectronic components. The components are disposed on a substrate with an interposed beam-splitting layer. The light incidence or light emission surface of the first optoelectronic element is disposed perpendicular to the substrate. The coupling system is either a bi-directional transmitter and receiver module or a mono-directional transmitter or receiver module. To this end, the light incidence or light emersion surface of the second optoelectronic element is disposed in parallel to the substrate and the beam-splitting layer is disposed on a surface that is arranged above the second optoelectronic element at an angle of approximately 45° with respect to the substrate.
Claims6
An optical coupling configuration for connecting an optical conductor to first and second optoelectronic components each having a light entry or light exit surface, comprising:
- a common substrate having parallel surface regions respectively carrying the optoelectronic components adjacent one another;
- wherein the optoelectronic components are arranged such that the light entry or light exit surface of the first optoelectronic component extends substantially perpendicular to said substrate and the light entry or light exit surface of the second optoelectronic component extends substantially parallel to said substrate;
- a molded part formed of an optically transparent material and having a first surface fastened on one of the light entry or light exit surfaces and a second surface;
- and
- a beam-splitting layer formed on said second surface above the second optoelectronic component and enclosing an angle of substantially 45° with said substrate.
An optical coupling configuration for connecting an optical conductor having a coupling end face to first and second optoelectronic components each having a light entry or light exit surface, comprising:
- a common substrate extending substantially parallel to the optical conductor and carrying the optoelectronic components adjacent one another;
- wherein the optoelectronic components are arranged such that the light entry or light exit surface of the first optoelectronic component extends substantially perpendicular to said substrate and the light entry or light exit surface of the second optoelectronic component extends substantially parallel to said substrate;
- and
- a beam-splitting layer formed on the coupling end face of the optical conductor and aligned above the second optoelectronic component to enclose an angle of substantially 45° with said substrate.
