The invention relates to an apparatus and a method for evaluating spectral properties of a measurement object. It comprises a plurality of light emission units, each emitting light with a predetermined emission spectrum and having a respective output configured for emitting the light with the predetermined emission spectrum onto the measurement object, an optical spectrograph having an input port adapted to receive light from the measurement object and a diffraction unit adapted to distribute different wavelengths of the received light to different output ports comprising the optical detectors, wherein the diffraction unit is adapted to distribute said received light to the respective output ports such that the lights in the respective output port have different wavelengths at different diffraction orders; a signal identification unit adapted to identify which of the light emission units contribute to the respective light in the respective output ports.

The invention relates to a method and a device for operating an optical transmitting device having a plurality of optical transmitters that can be driven independently. The method includes detecting the parameter values of the individual transmitters, comparing the parameter values determined with one another and/or with a prescribed comparison value, and selecting one of the transmitters for the communication operation of the transmitting device based on the comparison. The method further includes operating the transmitting device with the selected transmitter.

A semiconductor component has at least one Peltier element and at least one thermogenerator element that are thermally coupled to one another via a coupling device. By virtue of the thermal coupling of the Peltier element and the thermogenerator element through the coupling device, it is possible to use the Peltier element to cool a microstructure, in particular an optoelectronic component (e.g. a laser diode). Efficient temperature regulation and efficient operation of an optoelectronic component are thus possible.
