Abstract

The invention relates to an optoelectronic device including a transmitter designed to emit electromagnetic radiation and to be operated with an input voltage, and a receiver designed to receive the electromagnetic radiation and to provide an output voltage, the transmitter including at least one surface emitter, and the receiver comprising at least one photodiode.

First claim

The invention claimed is:

1 . An optoelectronic device comprising:
a transmitter configured to emit electromagnetic radiation and to be operated with an input voltage, a receiver configured to receive the electromagnetic radiation and to supply an output voltage, wherein the transmitter comprises two or more surface emitting lasers configured to emit electromagnetic radiation from different wavelength ranges, the receiver comprises two or more series-connected photodiodes coordinated with the different wavelength ranges and configured as detecting layers, between which are arranged tunnel diodes that interconnect the detecting layers in series with one another; and an optical unit that directs or guides the electromagnetic radiation from the transmitter to the receiver.

2 . The optoelectronic device as claimed in claim 1 ,
wherein the input voltage is less than the output voltage.

3 . The optoelectronic device as claimed in claim 1 ,
wherein the optical unit is integrated into a housing for the transmitter and the receiver or the optical unit is part of the housing.

4 . The optoelectronic device as claimed in claim 1 ,
wherein the optical unit is integrated into a potting body for the transmitter and the receiver or the optical unit is part of the potting body.

5 . The optoelectronic device as claimed in claim 1 ,
wherein the optical unit comprises two or more optical elements.

6 . The optoelectronic device as claimed in claim 1 ,
comprising a carrier having a top surface, wherein the transmitter and the receiver are arranged at the top surface and a radiation exit side of the transmitter and a radiation entrance side of the receiver are directed away from the top surface.

7 . The optoelectronic device as claimed in claim 1 ,
comprising a first carrier, on which the transmitter is arranged, and a second carrier, on which the receiver is arranged, wherein the first carrier and the second carrier are arranged opposite one another.

8 . The optoelectronic device as claimed in claim 1 ,
wherein at least one surface emitting laser has a resonator having a resonator axis running parallel to a main extension plane of an active region of the laser, wherein the laser is configured to the effect that the electromagnetic radiation leaves the laser transversely or perpendicularly with respect to the resonator axis.

9 . An optoelectronic device comprising:
a transmitter configured to emit electromagnetic radiation and to be operated with an input voltage, a receiver configured to receive the electromagnetic radiation and to supply an output voltage, wherein the transmitter comprises two or more surface emitting lasers configured to emit electromagnetic radiation from different wavelength ranges, the receiver comprises two or more series-connected photodiodes coordinated with the different wavelength ranges and configured as detecting layers, between which are arranged tunnel diodes that interconnect the detecting layers in series with one another; and an optical unit that directs or guides the electromagnetic radiation from the transmitter to the receiver, wherein the optical unit is integrated into a potting body for the transmitter and the receiver.
