In an optoelectronic component having a laser chip as a light transmitter and a lens coupling optics for defined emission of radiation generated in the laser chip, the lens coupling optics is arranged immediately in front of the laser chip and is adjusted and fixed in stable fashion in a simple way. The component is rationally manufactured in a wafer union. The laser chip is arranged on a common carrier between two carrier parts whose lateral surfaces neighboring the resonator faces of the laser chip are provided with mirror layers, and that are inclined at an angle of 45� relative to the resonator faces. Thus the radiation generated in the laser chip is directed nearly perpendicularly upward to the surface of the common carrier and the lens coupling optics is arranged on at least the one carrier part such that the radiation generated in the laser chip impinges this lens optics nearly perpendicularly.
1. An optoelectronic component for optical coupling between a semiconductor laser and a light conductor, comprising:a common carrier having two separate carrier parts separate from and mounted on the common carrier with a laser chip as a light transmitter in between the two carrier parts on the common carrier; said two carrier parts having lateral surfaces neighboring resonator faces of the laser chip, and respective mirror layers on the lateral faces which are inclined substantially at an angle of 45� relative to the resonator faces of the laser chip so that radiation generated in the laser chip is directed nearly perpendicularly upward from near a surface of the common carrier; a lens coupling optics formed as a separate lens chip for defined emission of radiation generated in the laser chip into said light conductor, said lens chip being arranged and secured on one of the carrier parts so that radiation generated in the laser chip impinges the lens chip substantially perpendicularly, said common carrier, said carrier parts and said lens chip having nearly a same coefficient of expansion, and said lens chip being formed of one of the elements selected from the group consisting of glass and semiconductor material; the two carrier parts being inserted into respective depressions in the common carrier; and a monitor chip arranged and secured on the carrier part on which the lens chip is not arranged and in a position so that a portion of the optical radiation generated by the laser chip is received by the monitor chip. 2. A component according to claim 1 wherein the common carrier is formed of silicon.
10. An optoelectronic component for optical coupling between a semiconductor laser and a light conductor, comprising:a common carrier having two separate carrier parts separate from and mounted on the common carrier with a laser chip as a light transmitter in between the two carrier parts on the common carrier; said two carrier parts each being shaped as trapezoids and having lateral surfaces neighboring resonator faces of the laser chip, and respective mirror layers on the lateral faces which are inclined at an angle of approximately 45� relative to the resonator faces of the laser chip so that radiation generated in the laser chip is directed upwardly and away from the common carrier; a lens coupling optics formed as a lens chip for defined emission of radiation generated in the laser chip into said light conductor, said lens chip being arranged and secured on one of the carrier parts so that radiation generated in the laser chip impinges the lens chip, said carrier parts and said lens chip having nearly a same coefficient of expansion, and said lens chip being formed of one of the elements selected from the group consisting of glass and semiconductor material; the two carrier parts being inserted into respective depressions in the common carrier; and a monitor chip arranged and secured on the carrier part on which the lens chip is not arranged and in a position so that a portion of the optical radiation generated by the laser chip is received by the monitor chip. 11.

Description
According to the invention, an opto-electronic component is provided having a laser chip as a light transmitter and a lens coupling optics for defined emission of radiation generated in the laser chip. The laser chip is arranged on a common carrier between two carrier parts whose lateral surfaces neighboring the resonator faces of the laser chip are provided with mirror layers that are inclined at an angle of 45� relative to the resonator faces. Radiation generated in the laser chip is directed nearly perpendicularly upward to a surface of the common carrier by the mirror layers. The lens coupling optics is arranged and secured on the at least one carrier part such that the radiation generated in the laser chip impinges this lens coupling optics nearly perpendicularly.
The optoelectronic component shown as a discrete component in FIG. 1 and shown in the wafer union in FIG. 2 is essentially composed of a laser chip 1 as a light transmitter, and of a lens coupling optics 6 for the defined emission of the optical radiation generated in the laser chip. The laser chip 1 is arranged on a common carrier 2 that is preferably composed of silicon and, as a submount, can be mounted on, for example, the bottom plate of a TO housing. The laser chip 1 is arranged on the common carrier 2 between two carrier parts 3, 4 whose side faces neighboring the optical resonator surfaces of the laser chip 1 are provided with mirror layers 5 and are inclined at an angle of 45� relative to the resonator surfaces, so that the coherent radiation generated in the laser chip 1 is deflected nearly perpendicularly upward to the surface of the common carrier 2. The two carrier parts 3, 4 are preferably composed of glass and have a trapezoidal profile. It is advantageous particularly for simplifying the adjustment and fastening of these two carrier parts 3, 4, to provide depressions or trenches mating therewith in the common carrier 2, the carrier parts 3, 4 being then introduced thereinto and secured therein. Layers of dielectric material are expediently applied onto the neighboring lateral surfaces of the carrier parts 3, 4 as mirror layers 5. The lens coupling optics 6 is arranged and secured on at least the one carrier part (the carrier part 3 in this exemplary embodiment), such that the radiation generated in the laser chip 1 impinges the optics 6 nearly perpendicularly.
