摘要:
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.

A transmission and reception module for a bidirectional optical communication and signal transmission includes a light transmitter having a first lens coupling optical element, and a light receiver. A fiber connection has a second lens coupling optical element for a common optical waveguide. A beam splitter is disposed in a free beam path. A common housing surrounds the foregoing. The light transmitter, the beam splitter and the fiber connection as well as the light receiver which is orthogonal thereto, are disposed axially symmetrically. An optical axis of the first lens coupling optical element is axially offset from an optical axis of the light transmitter, an optical axis of the second lens coupling optical element is axially offset from the optical axis of the fiber connection, the end surface of the fiber connection, given optimal coupling-in of light, has an angle of inclination relative to its optical axis, and the beam splitter is inclined relative to an axis of symmetry of the configuration, such that backreflected radiation strikes neither a radiation-active part of the light transmitter nor a radiation-sensitive part of the light receiver.

A method for hermetically fastening a glass fiber within a tube, wherein the tube can be used with light wave guide components, the tube serving as a connecting part at the component. The method provides for a tube consisting of quartz, quartz glass or glass. The glass fiber is connected to the tube at a predetermined fastening location by means of heating the tube and collapsing the tube to hermetically connect the glass fiber to the tube through melting.
