Title
(EN) OPTOELECTRONIC DEVICE WITH A COUPLING BETWEEN A SEMICONDUCTOR DIODE LASER MODULATOR OR AMPLIFIER AND TWO OPTICAL GLASS FIBERS
(FR) DISPOSITIF OPTOELECTRONIQUE POURVU D'UN COUPLAGE ENTRE UN MODULATEUR OU UN AMPLIFICATEUR A DIODE LASER A SEMI-CONDUCTEUR ET DEUX FIBRES DE VERRE OPTIQUES
Abstract
(EN)
The invention relates to an optoelectronic device with a module (1) comprising a holder (2) with an amplifier (3) and on either side thereof a lens (8) and a glass fiber (10) which can be aligned relative to the amplifier (3). The module (1) also comprises two monitor diodes (21). A disadvantage of the known device is that the lenses (8) cannot be easily aligned relative to the amplifier (3), and the monitor diodes (21) cannot be easily connected electrically. The use of aspherical lenses (8) also poses a problem. In a device according to the invention, the monitor diodes (21) are so positioned that they are capable of detecting radiation reflected at the outside of the lenses (8) instead of radiation refracted and reflected within the lenses (8), while the radiation-sensitive surfaces (22) of the monitor diodes (21) are positioned such that they receive more radiation from one lens (8) than from the other lens (8). This renders it possible to place the monitor diodes (21) on a separate, further holder (23) at some distance away from the amplifier (3) and the lenses (8), each being aimed at one of the two lenses (8). This facilitates both the alignment of the lenses (8) relative to the amplifier (3) and the electrical connection of the monitor diodes (21). The lenses (8), which now no longer bear on the monitor diodes (21) are also allowed to be aspherical now. Both the operation of the amplifier (3) and the value of the output signal can be monitored very well in this manner. The further holder (23) preferably has a T-shape with a wedge end (24) on which the monitor diodes (21) are present and which is immediately above the amplifier (3). The device according to the invention can be very compact. The angle ($g(a)) of the wedge portion (24) preferably lies between 45 and 90°.

L'invention porte sur un dispositif opto-électronique pourvu d'un module (1) comportant un support (2) avec un amplificateur (3) et, sur chacun de ses cotés, une lentille (8) ainsi qu'une fibre de verre (10) pouvant être alignées avec l'amplificateur (3). Ce module (1) comporte également deux diodes de contrôle (21). Le dispositif connu a pour désavantage la difficulté que l'on rencontre à aligner les lentilles (8) et l'amplificateur (3) ainsi qu'à établir une connexion électrique entre les diodes de contrôle (21). L'utilisation de lentilles (8) asphériques pose également un problème. Dans un dispositif selon l'invention, les diodes de contrôle (21) sont placées de façon à être en mesure de détecter un rayonnement réfléchi à l'extérieur des lentilles (8) au lieu de détecter un rayonnement réfracté et réfléchi dans les lentilles (8) tandis que leurs surfaces radiosensibles (22) le sont de façon à recevoir davantage de rayonnement d'une lentille (8) qu'elles n'en reçoivent des autres. Ceci permet d'installer les diodes de contrôle (21) sur un autre support (23), distinct, à quelque distance de l'amplificateur (3) et des lentilles (8), chaque diode étant dirigée sur l'une des deux lentilles (8). Cet agencement facilite tant la mise à l'alignement des lentilles (8) et de l'amplificateur (3) que la connexion électrique des diodes de contrôle (21). Les lentilles (8) qui ne portent plus, désormais, sur les diodes de contrôle (21) supportent d'être asphériques. Il devient, de la sorte, possible de contrôler efficacement tant le fonctionnement de l'amplificateur (3) que la valeur du signal de sortie. Le support supplémentaire (23) a, de préférence, une forme en T avec une extrémité conique (24) sur laquelle reposent les diodes de contrôle (21) et qui se trouve juste au-dessus de l'amplificateur (3). Le dispositif selon l'invention peut être très compact. L'ouverture de l'angle $g(a) de la partie conique (24) est comprise, de préférence, entre 45 et 90°.
