Abstract
Description
Die Erfindung betrifft eine optische Baugruppe zur Ankopplung eines Lichtwellenleiters mit einem lichtdurchlässigen Träger, und einem Sende- oder Empfangselement, das auf einer ersten Seite des Trägers aufgebracht ist. Darüber hinaus betrifft die Erfindung ein Verfahren zur Herstellung einer solchen optischen Baugruppe.The invention relates to an optical assembly for Coupling an optical fiber with a translucent carrier, and a transmission or Receiving element, which is on a first page of the Carrier is applied. Beyond concerns the invention a method for producing a such an optical assembly.
Eine derartige Baugruppe ist beispielsweise aus der Druckschrift DE 43 01 456 C1 bekannt. Der darin an gegebene plattenförmige Träger aus Silizium ist mittels mikromechanischer Fertigungsmethoden prä zise strukturiert, so daß ein als Sendeelement die nender Laserchip, ein Lichtwellenleiter und eine Abbildungslinse mit engen Toleranzen positioniert werden können. Die abschließende Justierung des Lichtwellenleiters des Laserchips ist aufgrund der präzisen Strukturierung deutlich vereinfacht. Um den sehr empfindlichen Laserchip von äußeren Ein flüssen zu schützen, ist er durch eine gehäusear tige hermetisch dichte Anordnung umgeben, wobei der Träger ein Teil der Einhäusung ist.Such an assembly is for example from the Document DE 43 01 456 C1 known. The one in it given plate-shaped carrier made of silicon using micromechanical manufacturing methods pre zise structured, so that a as a transmission element laser chip, an optical fiber and one Imaging lens positioned with tight tolerances can be. The final adjustment of the Optical fiber of the laser chip is due to the precise structuring significantly simplified. Around the very sensitive laser chip from outside To protect rivers, it is through a housing hermetically sealed arrangement, the Carrier is part of the enclosure.
Allgemein ist es auf jeden Fall erforderlich, der artige Halbleiterbauteile für ihren Einsatz in ein geeignetes Gehäuse zu montieren, an die der Licht wellenleiter optisch anzukoppeln ist. Dabei spielt insbesondere der Schutz der Bauteile vor Umgebungs einflüssen und eine gute optische Kopplung eine entscheidende Rolle bei der Auslegung der Gehäuse. Die Kopplung geschied dabei im allgemeinen durch eine Anordnung von ein bis zwei Linsen, wobei die Position der Lichtwellenleiter relativ zu den Lin sen und dem Laserchip in einem Justiervorgang opti miert wird. Der Laserchip ist in einem gegen die Umwelt hermetisch abgeschlossenen Gehäuse unterge bracht, wobei die Linsen und der Lichtwellenleiter entweder außerhalb angeordnet oder ebenfalls im Ge häuse angebracht sind. Im letzteren Fall wird der Lichtwellenleiter dann durch eine hermetische Durchführung aus dem Gehäuse ausgeleitet.In general, it is definitely necessary that like semiconductor devices for their use in a suitable housing to which the light optically couple the waveguide. It plays especially the protection of the components from the environment influence and a good optical coupling a decisive role in the design of the housing. The coupling generally passed through an arrangement of one or two lenses, the Position of the optical fibers relative to the Lin sen and the laser chip in one adjustment process is lubricated. The laser chip is in one against the Enclosed hermetically sealed housing brings, the lenses and the optical fiber either located outside or also in Ge housing are attached. In the latter case, the Optical fiber then through a hermetic Execution led out of the housing.
Aus dem Bereich der CD-Geräte sind Abtasteinheiten bekannt, bei denen lediglich der Laserchip zusammen mit einer Fotodiode zur Leistungsüberwachung in ein herinetisch dichtes Rundgehäuse montiert sind. Mitt lerweile wird diese Baugruppe auch für die Informa tionsübertragung genutzt. Das verwendete sogenannte Koaxialgehäuse ist ein feinmechanisches Produkt aus Metall und Glas und weist - gemessen an den Tole ranzforderungen für die optische Kopplung zwischen Laser und Lichtwellenleiter im Bereich von kleiner 1 µm - sehr erhebliche Fertigungstoleranzen auf, wes halb ein aufwendiger dreidimensionaler Justiervor gang zur Optimierung der Lichtwellenleiter-Ankopp lung notwendig ist.Scanning units are from the field of CD devices known in which only the laser chip together with a photodiode for performance monitoring in one herinetically sealed round housing are mounted. Mitt meanwhile this assembly is also used for the Informa tion transfer used. The so-called used Coaxial housing is a fine mechanical product Metal and glass and points - measured by the tole sancel requirements for the optical coupling between Lasers and optical fibers in the range of smaller 1 µm - very considerable manufacturing tolerances on what half an elaborate three-dimensional adjustment gear to optimize the fiber optic coupling is necessary.
Ein Nachteil der angesprochenen Verwendung von her metisch abdichtenden Gehäuse ist insbesondere darin zu sehen, daß Kosten verursacht werden, die bei sinkenden Halbleiterpreisen immer stärker ins Ge wicht fallen.A disadvantage of the use mentioned here Metically sealing housing is especially in it to see that costs are incurred at falling semiconductor prices increasingly into ge important fall.
Aus dem Aufsatz "Pig-tail Type Laser Modules Enti rely Molded in Plastic" Electronics Letters, 28. September 1995, Vol. 31, No. 20, Seiten 1745 bis 1747, ist eine Anordnung bekannt, bei der eine Laserdiode durch eine Kunststoffvergußmasse gegen Umgebungseinflüsse geschützt ist. Nachteilig ist dabei, daß die Laserdiode ohne Abbildungsoptik durch Stoßkupplung an die Glasfaser angekoppelt wird.From the article "Pig-tail Type Laser Modules Enti rely Molded in Plastic "Electronics Letters, September 28, 1995, Vol. 31, No. 20, pages 1745 to 1747, an arrangement is known in which one Laser diode against a plastic potting compound Environmental influences is protected. The disadvantage is doing that the laser diode without imaging optics coupled to the glass fiber by means of a coupling becomes.
Das erfindungsgemäße Verfahren mit den Merkmalen des Anspruchs 1 hat den Vorteil, daß auf ein teures das Sende- oder Empfangselement hermetisch ab dichtendes Gehäuse verzichtet werden kann, ohne den Schutz vor Umgebungseinflüssen, beispielsweise Feuchtigkeit, zu verlieren. Dadurch, daß eine lichtdurchlässige Schicht, beispielsweise eine op tisch transparente Vergußmasse auf den Träger und das Sende- oder Empfangselement aufgebracht wird, ergibt sich eine Abdichtung des Sende- oder Emp fangselements nach außen, einerseits durch den Trä ger selbst und andererseits durch die aufgebrachte Schicht.The inventive method with the features of claim 1 has the advantage that an expensive the transmitting or receiving element hermetically sealing housing can be dispensed with without the Protection against environmental influences, for example Losing moisture. The fact that a translucent layer, for example an op transparent potting compound on the carrier and the transmitting or receiving element is applied, there is a sealing of the transmission or emp catch elements to the outside, on the one hand through the door ger himself and on the other hand by the angry Layer.
Vorzugsweise wird eine wannenförmige Vertiefung auf einer Seite des Trägers ausgebildet, in die das Sende- oder Empfangselement vorzugsweise mittels einer Lotverbindung aufgebracht wird, wodurch ein zusätzlicher Schutz erreicht wird.A trough-shaped depression is preferably applied one side of the carrier into which the Transmitting or receiving element, preferably by means of a solder connection is applied, whereby a additional protection is achieved.
Vorzugsweise wird auf die erste Schicht eine wei tere Schicht aufgebracht, die als Feuchtigkeits sperre dient. Mit Hilfe dieses zweischichtigen Auf baus läßt sich eine Optimierung der ersten Schicht hinsichtlich der optischen und der zweiten Schicht hinsichtlich der abschirmender Wirkung besser be werkstelligen.A white layer is preferably applied to the first layer tere layer applied as a moisture lock serves. With the help of this two-layer opening The first layer can be optimized with regard to the optical and the second layer be better with regard to the shielding effect factory.
Vorzugsweise wird auf der anderen Seite des Trägers eine Linse ausgebildet, die einen besseren Koppel wirkungsgrad beim Ankoppeln eines Lichtwellenlei ters im Gegensatz zu einer Stoßkopplung erzielt.Preferably on the other side of the carrier formed a lens that has a better coupling efficiency when coupling an optical fiber ters achieved in contrast to a butt coupling.
Auch die erfindungsgemäße optische Baugruppe zur Ankopplung eines Lichtwellenleiters mit den Merkma len des Anspruchs 7 hat den Vorteil, daß ein das Sende- oder Empfangselement hermetisch abdichtendes Gehäuse nicht notwendig ist. Den Schutz des emp findlichen Sende- oder Empfangselements, vorzugs weise eine Laserdiode, vor äußeren Umgebungsein flüssen leistet nämlich eine optisch transparente Schicht, die das Sende- oder Empfangselement im we sentlichen umgibt und so nach außen hin abschirmt.The optical assembly according to the invention for Coupling an optical fiber with the feature len of claim 7 has the advantage that a Sending or receiving element hermetically sealing Housing is not necessary. The protection of the emp sensitive sending or receiving elements, preferred assign a laser diode, in front of external environment rivers provides an optically transparent Layer that the sending or receiving element in the we surrounds substantial and so shields from the outside.
Vorzugsweise ist das Sende- oder Empfangselement in einer wannenförmigen Vertiefung angeordnet, wobei dessen Strahlengang zu einer schrägen Wand der Ver tiefung gerichtet ist und über eine im Träger aus gebildete Reflexionsfläche zur unteren Seite des Trägers geleitet ist.The transmitting or receiving element is preferably in arranged a trough-shaped recess, wherein whose beam path to a sloping wall of ver deepening is directed and over one in the carrier formed reflection surface to the lower side of the Carrier is headed.

Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den übrigen Unteransprüchen.Further advantageous embodiments of the invention result from the remaining subclaims.
Die Erfindung wird nun anhand eines Ausführungsbei spiels mit Bezug auf die Zeichnung näher erläutert. Dabei zeigt die einzige Figur eine schematische Schnittdarstellung einer optischen Baugruppe. The invention will now be described with reference to an embodiment game explained with reference to the drawing. The only figure shows a schematic Sectional view of an optical assembly.
In der Figur ist eine optische Baugruppe 1 darge stellt, die eine vorzugsweise aus Silizium beste hende Trägerplatte 3 umfaßt.In the figure, an optical assembly 1 is Darge, which comprises a preferably best existing carrier plate 3 .
Auf einer oberen Seite 5 der Trägerplatte 3 ist eine wannenförmige Vertiefung 7 und eine dazu be nachbarte V-förmige Nut 9 mittels naßchemischer Ätzverfahren eingebracht.On a top side 5 of the carrier plate 3 , a trough-shaped recess 7 and a neighboring V-shaped groove 9 be introduced by means of wet chemical etching processes.
Auf einer Grundfläche 11 der Vertiefung 7 ist eine Halbleiter-Laserdiode 13 aufgesetzt, wobei zur Ver bindung eine Lotschicht 15 Verwendung findet. Die Laserdiode 13 selbst wird über eine elektrische Leitung 17 aktiviert, die an einem Kontaktpunkt 19 angebracht ist.On a base 11 of the recess 7 , a semiconductor laser diode 13 is placed, wherein a solder layer 15 is used for the connection. The laser diode 13 itself is activated via an electrical line 17 which is attached to a contact point 19 .
Benachbart zu der Laserdiode 13 ist eine Monitor- Fotodiode 21 auf der Oberseite 5 des Trägers 3 an geordnet. Die Monitor-Fotodiode 21 ist dabei zu ei ner schrägen Seitenfläche 23 der Vertiefung 7 ge richtet, um auf diese Weise von dort reflektiertes Licht aufnehmen zu können. Die Befestigung der Mo nitor-Fotodiode 21 erfolgt jedoch an der planen Oberseite 5 des Trägers 3, wobei wiederum eine Lot schicht 25 Verwendung findet. Selbstverständlich ist statt dem Lot auch ein Leitkleber einsetzbar. Die von der Fotodiode 21 abgegebenen Signale werden über eine elektrische Leitung 27, die an einem Kon taktpunkt 29 mit der Fotodiode verbunden ist, zu einer nicht dargestellten nachgeordneten Steuer- und Auswerteeinheit übertragen. Adjacent to the laser diode 13 , a monitor photodiode 21 is arranged on the top 5 of the carrier 3 . The monitor photodiode 21 is directed towards egg ner inclined side surface 23 of the recess 7 in order to be able to record light reflected from there. The attachment of the Mo nitor photodiode 21 , however, takes place on the flat upper side 5 of the carrier 3 , again using a solder layer 25 . Of course, a conductive adhesive can also be used instead of the solder. The signals emitted by the photodiode 21 are transmitted via an electrical line 27 , which is connected to the photodiode at a contact point 29 , to a downstream control and evaluation unit, not shown.
Die Figur läßt darüber hinaus eine Schicht 31 er kennen, die sowohl die Fotodiode 21 als auch die Laserdiode 13 vollständig umgibt. Lediglich die Verbindungsflächen mit der Oberseite 5 der Träger platte 3 kommen nicht in Kontakt mit dieser Schicht 31. Auch die Nut 9 ist von der Schicht 31 ausge füllt.The figure also shows a layer 31 , which completely surrounds both the photodiode 21 and the laser diode 13 . Only the connecting surfaces with the top 5 of the carrier plate 3 do not come into contact with this layer 31 . The groove 9 is filled out of the layer 31 .
Die Schicht 31 besteht aus einem optisch transpa renten Material, das eine definierte optische Brechzahl aufweist, die für die Berechnung des spä ter beschriebenen Strahlengangs wichtig ist.The layer 31 consists of an optically transparent material which has a defined optical refractive index, which is important for the calculation of the beam path described later.
Auf der kuppelförmigen Oberfläche der Schicht 31 ist eine weitere als Feuchtigkeitssperre dienende Schicht 33 aufgebracht. Dieser zweischichtige Auf bau wird immer dann benutzt, wenn die optisch transparente Schicht nicht ausreichende feuchtig keitssperrende Eigenschaften aufweist.A further layer 33 serving as a moisture barrier is applied to the dome-shaped surface of the layer 31 . This two-layer construction is used whenever the optically transparent layer does not have sufficient moisture-blocking properties.
Mit Hilfe der beiden Schichten 31 und 33 läßt sich die gegen äußere Einflüsse sehr empfindliche Laser diode 13 auf einfache Weise schützen.With the help of the two layers 31 and 33 , the laser diode 13 , which is very sensitive to external influences, can be protected in a simple manner.
Des weiteren ist der Figur zu entnehmen, daß auf einer unteren Seite 35 der Trägerplatte 3 eine op tische Linse 37 ausgebildet ist, die die Einkopp lung des Laserlichts in einen angeschlossenen Lichtwellenleiter verbessert.Furthermore, the figure shows that on a lower side 35 of the carrier plate 3, an optical lens 37 is formed, which improves the coupling of the laser light into a connected optical waveguide.
Die Herstellung einer optischen Baugruppe 1 erfolgt in mehreren Schritten, wobei als Grundmaterial ein Silizium-Wafer dient. In der Oberfläche der aus Si lizium bestehenden Trägerplatte 3 werden zunächst durch naßchemisches Ätzen Vertiefungen 7 und 9 aus gebildet, wobei die schrägen Wände 23 durch die Kristallrichtung definiert sind und deren Lage und Abmessung daher eine Präzision der Größenordnung 1 µm aufweisen.An optical assembly 1 is produced in several steps, a silicon wafer serving as the base material. In the surface of the carrier plate 3 made of silicon, depressions 7 and 9 are first formed by wet-chemical etching, the inclined walls 23 being defined by the crystal direction and their position and dimension therefore having a precision of the order of 1 μm.
Anschließend wird in die Vertiefung 7 die Laserdi ode 13 eingebracht, wozu das Lot 15 beispielsweise mit einem NdYAG-Laser punktuell erhitzt wird.The laser diode 13 is then introduced into the recess 7 , for which purpose the solder 15 is selectively heated, for example with an NdYAG laser.
Die Ausrichtung der Laserdiode innerhalb der Ver tiefung 7 erfolgt vorzugsweise in Längsrichtung an der Kante des Übergangs einer schrägen Wand 41 in die Grundfläche 11 der Vertiefung 7. Zusätzlich können an der Oberseite 5 der Trägerplatte 3 Mar kierungen zur Justierung vorgesehen sein.The alignment of the laser diode within the recess 7 is preferably carried out in the longitudinal direction at the edge of the transition of an inclined wall 41 into the base 11 of the recess 7 . In addition, 3 Mar markings can be provided for adjustment on the top 5 of the carrier plate.
Vor dem Aufbringen der Laserdiode kann zur Verbes serung der elektrischen Kontaktierung mit der Trä gerplatte 3 zusätzlich eine Goldschicht auf Teilen der Oberseite 5 aufgebracht werden. Neben der Ver besserung der elektrischen Leitfähigkeit dient diese - in der Figur nicht dargestellte - Goldschicht beispielsweise an der schrägen Wand 23 als Spiegel.Before the laser diode is applied, a gold layer can also be applied to parts of the top side 5 to improve the electrical contact with the carrier plate 3 . In addition to the improvement of the electrical conductivity, this gold layer - not shown in the figure - serves, for example, on the sloping wall 23 as a mirror.
Darüber hinaus werden die Grenzflächen der Träger platte 3, an denen Licht ein- oder austritt, mit einer Entspiegelungsschicht versehen, wofür eine Viertelwellenlängenschicht geeigneter Brechzahl, die ganz flächig auf beiden Seiten 5 und 35 abge schieden wird, ausreicht. In addition, the interfaces of the carrier plate 3 , where light enters or exits, is provided with an anti-reflective coating, for which a quarter-wavelength layer of suitable refractive index, which is completely separated on both sides 5 and 35 , is sufficient.
Wenn sowohl Fotodiode 21 als auch auch Laserdiode 13 aufgebracht sind, wird zunächst die Schicht 31 aufgebracht und anschließend die außenliegende Feuchtigkeits-Sperrschicht 33.If both the photodiode 21 and the laser diode 13 are applied, the layer 31 is applied first and then the external moisture barrier layer 33 .
Zur Ausbildung der Linse 37 wird eine Lacklinse, die durch Fotolithographie und Aufschmelzen des Lacks erzeugt wurde, ins Silizium übertragen. Eine andere Möglichkeit besteht darin, durch Ätzen einer wannenförmigen Vertiefung und selbstjustiertes Ein bringen einer Glaskugel eine Linse auszubilden. In beiden Fällen ist keine individuelle Justage not wendig, so daß der Justiervorgang nur einmal wäh rend der Herstellung der Trägerplatte erfolgt.To form the lens 37 , a lacquer lens, which was produced by photolithography and melting of the lacquer, is transferred into the silicon. Another possibility is to form a lens by etching a trough-shaped depression and self-adjusting a glass ball. In both cases, no individual adjustment is necessary, so that the adjustment process takes place only once during the manufacture of the carrier plate.
Letztendlich werden die einzelnen optischen Bau gruppen 1, die auf einem Wafer ausgebildet wurden, durch Sägen oder Brechen vereinzelt. Aufgrund der Schichten 31 und 33 und der versenkten Anordnung der Laserdiode 13 bleibt diese dabei unbeschädigt. Zum Schutz vor Verunreinigungen läßt sich vor dem Vereinzeln die Unterseite 35 mittels einer Lack schicht schützen.Ultimately, the individual optical construction groups 1 , which were formed on a wafer, are separated by sawing or breaking. Due to the layers 31 and 33 and the recessed arrangement of the laser diode 13 , this remains undamaged. To protect against contamination, the underside 35 can be protected by means of a lacquer layer before separation.
Darüber hinaus können bei der Herstellung auf der Unterseite 35 zusätzliche Justiermarken angebracht werden, die bei der abschließenden optischen Kopp lung der vereinzelten Baugruppen mit dem beispiels weise auf einer ähnlichen Trägerplatte angebrachten Lichtwellenleiter zur Vorausrichtung dienen, so daß der notwendige Justiervorgang vereinfacht und be schleunigt wird. In addition, 35 additional alignment marks can be attached to the manufacture on the underside, which serve for pre-alignment in the final optical coupling of the individual modules with the example, attached to a similar carrier plate, so that the necessary adjustment process is simplified and accelerated.
Im folgende soll nun kurz auf die Funktions der op tischen Baugruppe eingegangen werden.In the following we will briefly look at the function of the op table assembly.
Die Laserdiode 13 emittiert Laserlicht in einem Wellenlängenbereich oberhalb 1100 nm in Richtung der schrägen Wand 41 der Vertiefung 7. Aufgrund der optischen Transparenz für diesen Wellenlängenbe reich der Schicht 31 erreichen die Strahlen die Wand 41, wo sie zum Lot hin gebrochen werden. Vor aussetzung dafür ist jedoch, daß das Material der Schicht 31 eine entsprechende Brechzahl besitzt. Das Licht breitet sich dann innerhalb der ebenfalls für den angegebenen Wellenlängenbereich durchlässi gen Trägerplatte 3 weiter aus und trifft auf eine schräge Wand 43 der V-förmigen Nut 9. Dort wird dann das Licht nach unten zur Unterseite 35 reflek tiert. Nachdem es die Trägerplatte 3 durchquert hat, tritt es an der Unterseite 35 aus. Soll das Laserlicht anschließend in einen Lichtwellenleiter eingekoppelt oder als kollimierte Strahl verwendet werden, ist an der Austrittsstelle die Linse 37 an geordnet.The laser diode 13 emits laser light in a wavelength range above 1100 nm in the direction of the inclined wall 41 of the depression 7 . Because of the optical transparency for this wavelength range of the layer 31 , the rays reach the wall 41 , where they are refracted towards the solder. Before it is possible, however, that the material of the layer 31 has a corresponding refractive index. The light then spreads further within the carrier plate 3, which is also permeable for the specified wavelength range, and strikes an inclined wall 43 of the V-shaped groove 9 . There the light is then reflected down to the bottom 35 . After it has passed through the carrier plate 3 , it emerges from the underside 35 . If the laser light is then to be coupled into an optical waveguide or used as a collimated beam, the lens 37 is arranged at the exit point.
Zur Überwachung der Funktion der Laserdiode 13 und zur Regelung der Ausgangsleistung bei Temperaturän derungen und Alterung, strahlt die Laserdiode 13 Licht zu der schrägen Wand 23, an der es zu der Fo todiode 21 hin reflektiert wird.To monitor the function of the laser diode 13 and to regulate the output power in the event of changes in temperature and aging, the laser diode 13 emits light to the inclined wall 23 , on which it is reflected toward the photodiode 21 .
Besondere Bedeutung bei dieser optischen Baugruppe kommt dem Material der Schicht 31 zu. Diese muß - wie bereits erwähnt - eine definierte Brechzahl auf weisen, die darüber hinaus konstant und reprodu zierbar ist. Zusätzlich muß sie frei von beispiels weise durch Füllstoffe verursachte Streuzentren, sein und eine hohe Transparenz bei der Emissions wellenlänge der Laserdiode 13 aufweisen. Letztend lich ist es auch notwendig, daß das Material eine geringe Wärmeausdehnung besitzt.The material of the layer 31 is of particular importance in this optical assembly. As already mentioned, this must have a defined refractive index which is also constant and reproducible. In addition, it must be free of, for example, scattering centers caused by fillers, and have a high transparency in the emission wavelength of the laser diode 13 . Ultimately, it is also necessary that the material has a low thermal expansion.
In einer nicht dargestellten Ausführungsform der Er findung ist die Vertiefung 7 in zwei Stufen ausge führt. Dabei wird der Laserchip 13 so auf die Grundfläche 11 der höherliegenden Stufe montiert, daß der lichtemittierende Bereich direkt auf der Lotschicht aufliegt (Epi-down-Montage). Gleichzei tig liegt die Endfläche an der Kante des Übergangs von der höherliegenden zur niedriger liegenden Stufe, so daß das Licht zunächst ebenfalls in den mit der Schicht 31 gefüllten Raum emittiert wird, bevor es an der schrägen Seitenwand 41 in den Trä ger übergeht. In dieser Anordnung kann der Abstand zwischen der Laserdiode 13 und der Seitenwand 41 geringer eingestellt werden, was für Laserdioden mit großem Öffnungswinkel der Emission vorteilhaft sein kann.In an embodiment of the invention, which is not shown, the recess 7 is in two stages. The laser chip 13 is mounted on the base 11 of the higher level in such a way that the light-emitting area lies directly on the solder layer (epi-down mounting). At the same time, the end face lies on the edge of the transition from the higher to the lower step, so that the light is also first emitted into the space filled with the layer 31 before it passes on the inclined side wall 41 into the carrier. In this arrangement, the distance between the laser diode 13 and the side wall 41 can be set smaller, which can be advantageous for laser diodes with a large emission angle.
