The invention provides an optoelectronic device having a holder and a coxial module which is secured in the holder and which includes an optoelectronic component, preferably a semi-conductor diode laser. The module is capable of receiving or emitting radiation at an end face of the module, preferably via a coupled glass fiber. Connection pins for the optoelectronic component are situated at the other end face of the module and the holder is provided with connection means which extended right angles to the longitudinal direction of the module and that are electrically connected to the connection pins. The connection pins are bent from the longitudinal direction of the module towards the connection means. The free ends of the connection pins are inserted in the connection means. The holder is provided with a clamping member by means of which the module is secured in the holder. The clamping member is constructed in such a manner that the module can be placed in the clamping member of the holder in a direction at right angles to the longitudinal direction of the module.

Holder for optoelectronic device having connection pins bent toward a

The invention relates to an optoelectronic device with a module comprising a holder with an amplifier and on either side thereof a lens and a glass fiber which can be aligned relative to the amplifier. The module also comprises two monitor diodes. A disadvantage of the known device is that the lenses cannot be easily aligned relative to the amplifier, and the monitor diodes cannot be easily connected electrically. The use of a spherical lenses also poses a problem. In a device according to the invention, the monitor diodes are so positioned that they are capable of detecting radiation reflected at the outside of the lenses instead of radiation refracted and reflected within the lenses, while the radiation-sensitive surfaces of the monitor diodes are positioned such that they receive more radiation from one lens than from the other lens. This renders it possible to place the monitor diodes on a separate, further holder at some distance away from the amplifier and the lenses, each being aimed at one of the two lenses. This facilitates both the alignment of the lenses relative to the amplifier and the electrical connection of the monitor diodes. The lenses, which now no longer bear on the monitor diodes are also allowed to be a spherical now. Both the operation of the amplifier and the value of the output signal can be monitored very well in this manner. The further holder preferably has a T-shape with a wedge end on which the monitor diodes are present and which is immediately above the amplifier. The device according to the invention can be very compact. The angle of the wedge portion preferably lies between 45.degree. and 90.degree..

Optoelectronic device with a coupling between a semiconductor diode

Optoelectric device having a coupling between a semiconductor diode laser component, such as an amplifier or modulator, and two optical glass fibres. The optoelectronic device has an optoelectronic module comprising a first holder with a semiconductor diode laser component and provided on either side of the component with a second holder comprising a plate with an opening and a lens holder in which a lens is present. The module also comprises a third holder for an optical glass fibre aligned with the component on either side of the component. The second holder comprises a bush which is connected to the plate and within which the lens holder is fastened to the plate, while the bush is provided with at least one opening, near the plate.

An optoelectronic device with an optoelectronic module containing a semiconductor diode laser device and, in the radiation path (S) on either side of the semiconductor diode laser device, in that order, a first lens, an optical component, in particular an optical isolator, a second lens, and an optical glass fiber. The second lens and the glass fiber are arranged in a sub-module. The optical component is present in the sub-module and the first lens outside it, and the module is provided with means for fastening the sub-module to the module at an adjustable angle relative to the radiation path. Said means preferably comprise a membrane and radially adjustable clamping means.
