Definitions
- the invention relates to an optoelectronic coupling element and a method for its production.
- the optoelectronic coupling element comprises a coupling part which has coupling means for coupling light from a light path into at least one light guide element and / or for coupling light from the at least one light guide element into the light path, a component carrier with at least one opto semiconductor arranged thereon and deflection means for forming the light path between the coupling means and the at least one optical semiconductor.
- Such optoelectronic coupling elements are used to produce a coupling between light-generating or light-receiving optoelectronic components and light-guiding elements, in particular optical waveguides.
- a method for producing an optoelectronic connector receptacle element and an optoelectronic connector are known from the publication DE 197 43 992 C1.
- the known connector receptacle contains a mounting block with two alignment pins which, when the connector receptacle element is joined together with an optical connector, are inserted into holes which are formed in the optical connector in order to achieve an adjustment of the optical waveguides arranged in the connector with respect to the optoelectronic component arranged on a component carrier ,
- the optical fibers are arranged opposite coupling means, the light generated by the optoelectronic component and with the aid of
- Deflection means has been directed to the coupling means, couple into the optical fiber or light from the Couple optical fibers into the light path in the deflecting means in order to guide the light coupled out of the optical fibers to the optoelectronic part, which in this case is designed as a receiver element.
- the deflection means comprise optical elements or components for the low-loss transmission of the light, for example lenses or total reflection surfaces.
- the coupling means, the deflecting means and the optoelectronic component or the component carrier are arranged in a certain manner relative to one another.
- the present invention has for its object to provide an optoelectronic coupling element of the type described in the opening paragraph, in which there is an improved possibility for optimizing the light path between the coupling means and the optical semiconductors.
- the invention is based on the essential idea that the deflection means used to form the light path between the optical semiconductor and the coupling means should be designed in several parts so that an adjustment of the multi-part deflection means can be used to create an optical path that is optimized in terms of the low-loss transmission of light when producing the optoelectronic coupling element ,
- Component carrier with the optical semiconductor relative to the Deflection means moved.
- the main advantage of the invention over the prior art is that the relative movement of the optical and other optical deflecting means enables a fine adjustment of the light path.
- a further major advantage is that the proposed manufacturing process can be used in conjunction with conventional component carriers without the component carriers having to be changed in terms of construction.
- deflection means that the deflection means can be used in conjunction with different coupling means and component carriers, certain parts of the deflection means being usable for different coupling means or component carriers and other parts of the deflection means being individually adaptable to the different coupling means or component carriers.
- An expedient development of the invention provides that after the arrangement of the other optical deflection means, a further optical deflection means is arranged in order to form a further light path between the coupling means and a further optical semiconductor on the component carrier, so that the optoelectronic coupling element acts as a transmitting / receiving element is trainable.
- Transceiver components can be produced using the proposed method.
- a further development of the invention provides that after arranging the other and / or the further optical deflection means, the component carrier is adjusted in order to roughly adjust the light path between the coupling means and the to carry out at least one optical semiconductor and / or the further light path between the coupling means and the further optical semiconductor, whereby a further optimization of the light path or of the further light path is made possible.
- a preferred embodiment of the invention in terms of simple adjustment of the component carrier provides that the component carrier is passively adjusted with the aid of a vo jump arranged on the optical deflection means, the projection being arranged in a recess formed on the component carrier.
- the other and / or the further optical deflection means for adjustment are essentially shifted in one plane, whereby a higher accuracy of the adjustment can be achieved since the relative movement of the other and / or the further optical deflection means with respect to Degrees of freedom is limited, the use of which in the adjustment generally only makes an insignificant contribution to optimizing the light path or the further light path.
- a fixing of the deflecting means after the adjustment which can be carried out with little effort and inexpensively, provides that an adhesive is applied in order to fix the other and / or the further optical deflecting means in such a way that no impairment of the light path and / or the further light path occurs.
- An expedient further development of the invention provides that after the other and / or the further optical deflection means have been fixed, adjustment means which are designed for adjustment to the other and / or the further optical deflection means are removed.
- the adjustment means With the help of the adjustment means on the one hand the possibility is created of being able to move the other and / or the further optical deflecting means with sufficient accuracy during the adjustment.
- the adjustment means after completion of the adjustment and fixing the other and / or the other optical
- Deflection means are removed so that the most compact possible design of the optoelectronic coupling element is supported.
- An embodiment of the invention which is preferred in relation to the lowest possible production outlay provides that the adjustment means are removed from the other and / or the further optical deflection means by breaking off in the region of a predetermined breaking point.
- Figure 1 shows an optoelectronic coupling element in cross section
- Figure 2 shows the optoelectronic coupling element according to Figure 1 in side view.
- an optoelectronic coupling element 1 has a coupling part 2 with alignment pins 3, 4.
- the alignment pins 3, 4 serve to fix a plug (not shown) with respect to a first and a second light passage opening 5, 6 formed in the coupling part 2, in order to allow light to pass through, that emerges from optical fibers in the connector or is coupled into the optical fibers.
- the alignment pins 3, 4 engage in holes in the connector (not shown) when arranging the connector with the optical fibers, so that the optical fibers are relative to the first and the second
- Light passage opening 5, 6 are arranged.
- the first and the second light passage opening 5, 6 are preferably designed so that the optical waveguides in the connector can have a central distance of about 750 microns.
- the first and the second light passage opening 5, 6 are connected to coupling means 7.
- the aid of the coupling means 7 light is guided from the optical waveguides of the plug (not shown) into an optical deflecting part 8 or coupled from the optical deflecting part 8 into the optical waveguides.
- light is coupled into an optical waveguide which is connected to the first light passage opening 5 with the aid of the coupling means 7, the light being transmitted through the optical deflection means 8 along a light channel 9.
- light from an optical waveguide, which is connected to the second light passage opening 6, is coupled into another light channel 10 in the optical deflection means 8. This is shown schematically with the aid of arrows A and B in FIG. 1.
- the first light passage opening 5 is part of a transmission channel
- the second light passage opening 6 is part of a reception channel.
- the light is conducted in one and the other light channel 9, 10 in each case using reflections, for example by means of total reflections, metallic or dielectric mirroring.
