An electrooptical transmitting and/or receiving module has a lead frame and an optoelectronic transducer mounted thereon. The lead frame and the optoelectronic transducer are potted by a shaped body made from transparent, formable material. Introduced into the shaped body is a reflector element. A radiation beam emitted by a transmitter, or a received radiation beam to be directed onto a receiver is deflected at a prescribed angle by the reflector element. The module can be used in an electrooptical transmitting and/or receiving unit which is constructed as a sidelooker. A method is also provided for molding the electrooptical transmitting and/or receiving module.

Electrooptical transmitting/receiving module, and method for producing the module

An electro-optical data transmission module comprises at least a first SMT housing ( ) and a second SMT housing ( ). A surface-emitting laser light emitter chip is accommodated in the first SMT housing ( ), and a light-sensitive light receiver chip is accommodated in the second SMT housing ( ). By virtue of the modular design which is formed from at least two individual SMT housings, the electro-optical data transmission module can be implemented with a minimum size.

Electro-optical data transfer module

A transmission and reception device, in which the transmission device and the reception device and the input/output end of a glass fiber are disposed optically in series with respect to one another. A laser diode is disposed on a central part of a photosensitive surface and the input/output end of the glass fiber is in turn adjusted in front of its end face. As a result of a cylindrical symmetry of the photosensitive surface and of the laser diode with respect to a fiber axis, a maxima of the coupling curves coincide with the fiber axis, so that a lateral fiber offset leads to only a moderate change in coupling efficiency.

Two-way optical transmission and reception device

A module essentially includes a module housing, into which is introduced a lead frame. An electro-optical transducer is mounted on the lead frame. The interior of the module housing is filled with a transparent potting compound. A plug receptacle part is moulded onto the outer housing wall and has a defined outer contour. Situated in the interior of the plug receptacle part is an optical waveguide piece, which proceeding from the surroundings of an outer area of the plug receptacle part, extends through the interior of the plug receptacle part and through a housing opening right into the housing interior. The optical waveguide piece is optically coupled to the electro-optical transducer. An optical waveguide plug interacting with the module has a sleeve-shaped plug section corresponding to the plug receptacle part.

Optical transmitting/receiving module including an internal optical waveguide

A method for producing an electrooptical module having a molding made of a translucent, moldable material, includes positioning a support with an electrooptical transducer in a mold. The support with the transducer is encased by a moldable material to form the molding and the mold has at least one functional surface for coupling. In order to permit and facilitate the production of an electrooptical transducer with a very precisely positioned functional surface and a high mechanical strength, a dead mold is used in the form of a module housing having an opening for the introduction of the support and a coupling region for a coupling partner. A housing part which is located in the coupling region is configured to correspond to the functional surface. A mold for producing an electrooptical module, and an electrooptical module, are also provided.
