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.
Claims9
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.
