Definitions
- Optical interconnection module, and ferrule comprising such a module
- An optical fiber is mainly used as a means of transporting information, in the form of light signals, normally digitized.
- This means of transport has the advantage of effectively resisting noise, in particular electromagnetic noise, and also allowing very high information rates.
- the processing in current computer devices being of electronic type, it is important to make an optoelectronic conversion of the light signals to be processed, at the input and at the output of the optical fiber.
- optical fibers can be butted together, it is important to be able to connect them effectively.
- Various solutions have been devised to resolve these conversion and / or connection problems.
- the optical fiber or a layer of optical fibers is provided at its two ends (or at least at one of its ends), in a fixed manner, with an optoelectronic conversion device.
- the optical fiber delivers electrical or electronic signals at one or both ends while it can deliver optical signals at another end.
- the disadvantage presented by this type of solution is on the one hand the cost generated by this integration of means.
- the workability of the fiber is greatly reduced. Indeed, it is easily understood that the length of the fiber cannot be adjusted as easily as one would like, a fortiori if it is provided on either side with electronic conversion circuits crimped at the ends of the fibers.
- the mode of transmission in optical fibers can depend on the single-mode or multi-mode nature of the fiber and or on the device for injecting light rays into the fiber. Then, during the injection or
- the housing is formed in two half-shells which are assembled around the overmolding material.
- the grooves will be Vee, circular cylindrical, circular semi-cylindrical, or other, their direction
- the lenses are obtained either by placing the ends of the ferrule an excess of overmolding material which naturally adopts a form of lenses having a focusing power, or by producing grooves whose transverse profile evolves, in particular in the form of a cone, at the ends of a section of optical guide thus made in the housing.
- flares are produced at low cost allowing focal adaptation, either at the connection between two optical fibers, or at the connection between a transport optical fiber and an optoelectronic conversion circuit.
- the invention therefore relates to an optical interconnection module comprising a housing provided with at least one optical section interposed between an optical input port of the module and an optical port output of the module, characterized in that the optical section is molded into the housing and forms an optical waveguide, in that the optical fiber section has at least one widening cone increasing at one end of the section and forming an optical output section, and in that the optical section has an end lens.
- Figures 1a and 1b representations in longitudinal sections, in two perpendicular planes, of the optical module of the invention
- FIG. 2 a sectional representation of an example of an integration of a module according to the invention in a complete optoelectronic ferrule of conversion;
- Figure 3 a section showing an alternative embodiment of the integration of Figure 2.
- FIG. 1a and Figure 1b show an optical module 1 according to the invention.
- This module 1 comprises a box 2 provided with at least one optical section 3, of optical fiber in one example, more generally of light wave guide.
- the waveguide 3 is interposed between an optical input port 4 and an optical output port 5 of the module.
- FIG. 1b it can be seen that several optical sections such as 3 and 6 to 8 are stored side by side, preferably parallel to each other, in the housing 2.
- Overall the housing has a parallelepiped shape.
- the housing 2 is formed of a base made of at least one first material 9 (FIG. 1a) in which the sections 3 or 6 to 8 of the waveguide are overmolded.
- the waveguide sections are made of another material.
- the material 9 of the base may preferably be a plastic material of amorphous structure, for example of the same material (COC, cyclo-olefin-copolymer) as the material constituting the waveguide sections.
- At least the material 10 will be transparent to light rays.
- the material 9 will also be so and will have a refractive index, n2, lower than a refractive index or of the material 10 forming the waveguides.
- n2 refractive index
- the molding solution thus presented also allows, by micro-sculpture techniques, to impose for the waveguide 3, or for the sections 6 to 8, a set of particularly interesting shapes.
- the micro-structuring techniques can be stamping techniques, or hot embossing techniques, or else be photolithography techniques with chemical etching, or even laser engraving techniques.
- the aim is to produce grooves capable of receiving the overmolding material 10.
- the overmolding material itself can be implemented by micro-injection techniques, the conduit produced in the material 9 having an inlet and an outlet and thus being suitable for injection.
- the housing 2 made of material 9 may comprise a body formed by a base 11 and a cover 12.
- the base and the cover may both be made of the same material, for example transparent with a lower coefficient of refraction n2 to the refractive coefficient of the material 9 waveguide 3.
- the cover 12 it would also be possible for the cover 12 to be produced with a gel having an adequate refractive index.
- a base 13 is preferably preferably first made of a material capable of easily accepting the material 9 of the base 11.
- the material of the base 13 in the context of a plastic embodiment, will be a PBT, poly-butylene-terephthalate, a polyimide, or a crystalline or semi-crystalline polymer having good mechanical strength such as polymers with liquid crystal (LCP).
- LCP liquid crystal
- the cover 12 can itself be mounted in a cap 14 having the same function and the same nature as the base 13 with respect to the base 11.
- the base 13 will be provided with reliefs such as 15 , with free edges, in the form of grooves or studs, allowing an efficient and industrially durable attachment of the material 9 of the base 11 on this base 13. The same will be done, where appropriate, for the cover 13 with respect to the cap 14 .
- the base 11 is thus overmolded on the base 13.
- this base 11 is polymerized and then sculpted, by etching or otherwise, to make conduits there, in particular in the form of grooves intended to serve subsequently as a guide. light waves.
- These sculpted conduits are then in turn filled with a molding material 10 intended to form light wave guides 3.
- the cover 12 is put in place and the material 10 is polymerized so as to stiffen it.
- the polymerization is prior to the establishment of the cover 12, the surface of the assembly thus produced can also be rectified before the establishment of this cover 12. In this case, the latter is not necessarily itself - even provided with grooves.
- the optical fiber sections 3 are provided, preferably in the inlet port 4 and in the outlet port 5, but at least in one of these, with cones flares such as 16 and 17 respectively. They are preferably even surmounted by lenses such as 18 and 19. It is also possible to produce the sections without flaring, but with the lenses, just as it is possible to produce the sections with the flares but without the lenses.
- the flares have an effect of improving the optical transfer.
- the lenses 18 and 19 have a focusing or collimation effect which will be explained later.
- the lenses are obtained by the installation of a mold 20 for overmolding when the guides of waves 3 are overmolded.
- the lenses are thus made of the same material as the material 10 of the waveguides 3, and at the same time as these waveguides 3.
- the flares 16 and 17 are such that the waveguide section 3 , of optical fiber, has over the length of the housing a smaller diameter, or a smaller section, than the diameter or the section at the inlet of the inlet port 4 or at the outlet of the outlet port 5.
- the shape of the section of the waveguide in the longitudinal part can be circular, or polygonal, preferably square or rectangular in this case.
- the length of each of the flares 16 and 17 is of the order of a tenth of the length of the sections 3.
- the box 2 is more complete, in particular that the input port 4 comprises a receptacle 21 for receiving a standardized tip 22 mounted on a sheet 23 of optical fibers 24 to 27. It forms a ferrule provided of the module of FIGS. 1a and 1b.
- the number of optical fibers in the sheet 23 is of course preferably the same as that of the sections of optical fiber in the ferrule.
- the emitting or receiving ends such as 28 of the optical fibers of the sheet 23 then see, according to the invention, each respectively a field 29 formed by a lens entry face such as 18. This field 29 is larger than these ends 28. Consequently, the energy transfer to or from the fiber section 3 is much more efficient.
- the housing 2 of the ferrule 1 comprises the output port 5 also provided with lenses 19. These lenses are here placed opposite integrated circuits 30 for detecting or emitting light rays. These integrated circuits 30, individualized and in number equal to the number of sections 3, are themselves placed on an integrated control circuit 31.
- the integrated circuits 30 are placed very rigorously on the control circuit 31 by an assembly by refusals of solder balls, surface tensions appearing in these solder balls at the time of soldering and allowing a setting in perfect place (with a tolerance of less than one micrometer) of these integrated circuits 30 at selected locations on this integrated circuit 31.
- the control circuit 31 is itself mounted on the housing 2 by refusals of solder balls 32 allowing a precise placement of connection pads 33 of the circuit 31 relative to metallized areas 34 formed on the housing 2.
- the base 13 or the cap 14 which are made of materials which withstand very high temperatures allow these rejections.
- the ferrule 1 provides the optoelectronic connection inexpensively between the circuits 30 and 31 and the sheet 23 of optical fibers.
- Figure 3 shows an alternative embodiment of the ferrule of Figure
- the base 13 has a right foot 36 end opposite to the inlet port 4, very high, rising towards a cover, not shown, of the ferrule.
- Figure 3 is presented along a plane perpendicular to the plane of Figure 2.
- the web 23 is seen by the edge.
- the sections 3 have there the particularity of having an elbow 37 making it possible to ensure that the outlet port 5 is not in a rectilinear alignment of the inlet port 4 along the section 3.
- Such an elbow 37 plays the same role as a mirror of the cited state of the art, but at a lower cost.
- the circuit 30, and the circuit 31 can be found in a plane of a printed circuit, not shown, which carries the ferrule 1 (or in a parallel plane).
- the elbow 37 would be oriented towards the plane of the studs 35.
- the base 13 could be drilled in their place to allow the material 9 of the base 11 and the material 10 of the guides to open out.
- the production by overmolding can include the production of several vertical sections in which grooves are made, with a butt-shaped end (provided or not at the end of the butt with a flare 17).
- the different sections are then joined to one another and the material which must constitute the sections 3 is injected into the galleries thus formed by assembling sections against each other.
- the slices are provided with a groove on one side only, these are filled, flat by overmolding of the material 10. Then the slices are assembled one against the other, after possible rectification.
- This embodiment then makes it possible to present the integrated circuit 31 (provided with its integrated transmission circuits or detection 30) parallel to a plane of a general printed circuit on which the ferrule 1 is placed.
- metallized connections 38 originating from metallizations 34 produced in the housing 2 lead along the right foot 36, up to studs 35.
- the metallizations of studs 35 allow the electrical connection of the circuit 31 to a receiving printed circuit as well as maintaining by soldering the ferrule 1 on this receiving printed circuit.
- the lenses 18 or 19 in a material with a refractive index different from the material used to form the sections 3 and the flares 16 and 17. However, preferably, the same material will be used, for reasons of simplification. Manufacturing.
