摘要:
One or more aspects of the invention relate to an optical or electronic module with at least one optical or electronic component and a plastic package within which the component is embedded. The component has an operative region that facilitates operative connection with surroundings. The plastic package has a first region, which comprises a transparent polymer compound, and a second region, which comprises a non-transparent polymer compound. The first region extends such that it borders the operative region of the component.

The invention relates to a method for producing an optical or electronic module provided with a plastic package. The method includes provision of at least one optical or electronic component, the component having an operative region via which it is in operative connection with the surroundings in the finished module, and application to the component of a protective layer which covers at least the operative region of the component. The method further includes encapsulation of the at least one component with at least one polymer compound to form the package, and partial removal of the polymer compound from the outside by a laser ablation device such that the polymer compound between the protective layer of the component and the outer side of the plastic package is removed. The protective layer is, in this case, not transparent with respect to the radiation emitted by the laser ablation device. The invention relates furthermore to an optical or electronic module with at least one optical or electronic component, to which a protective layer is applied.

The invention relates to an arrangement for optically coupling an optical waveguide to an optical unit of an optical module. The optical module has a reference geometry, which defines a first axis of symmetry. There is an offset between the optical axis of the optical unit and the axis of symmetry of the reference geometry. The invention provides a coupling element which eliminates the offset. The coupling element has, for this purpose, a hole, which is delimited by an inner surface, the inner surface of the coupling element defining a second axis of symmetry. The first axis of symmetry and the second axis of symmetry extend parallel to one another and have an offset with respect to one another which is essentially the same as the offset between the optical axis of the optical unit and the first axis of symmetry of the reference geometry as regards direction and magnitude. Furthermore, a beam-shaping element having an optical axis, which coincides with the second axis of symmetry, is provided on that side of the coupling element which faces the optical unit.

Various embodiments of arrangements for optically coupling an optical waveguide to an optical unit of an optical module are provided. One embodiment is an optical module for optically coupling an optical waveguide to an optical unit. One such optical module comprises: a reference structure having a reference geometry that defines a first axis of symmetry; an optical unit having an optical axis along which light is transmitted or received, the optical unit positioned relative to the reference structure with an offset between the first axis of symmetry and the optical axis; and a coupling element that couples the optical unit to an optical waveguide, the coupling element having an eccentric hole which functions as a fiber guide and a structural geometry adapted to compensate for the offset between the first axis of symmetry and the optical axis.

In a modular system of optoelectronic components each component has a standardized housing. The standard housing has a device for the mechanical connection to at least one housing of a further component, or it is connected to such a device. This allows different combinations to be produced using the same system components. Flat optoelectronic components are particularly suitable for use in the modular system. In this case, according to the invention, an optical waveguide is integrated in the component, runs parallel to a circuit mount, and forms an optical interface on one narrow housing face. The electrical contacts of the component are likewise arranged on a narrow housing face.

An optoelectronic transceiver module includes a coupler and an optoelectronic transmitter and receiver. The coupler couples one optical waveguide of one optical network. The coupler and network each have a reflection impulse response. The transceiver has a compensator generating an electrical correction signal using characteristic parameters of the reflection impulse response of the coupler and/or optical network and the electrical data signals of the transmitter, and uses the correction signal to correct the data signals received by the receiver. In the method, optical signals are received in a first transceiver from a second transceiver. Characteristic parameters of the reflection characteristics of the optical system coupled to the receiver in the first transceiver are determined, these parameters are used to generate a correction signal from the data signal to be sent from the first transceiver, and an electrical received signal is corrected in the first transceiver using the correction signal.
