Abstract

The semiconductor device comprises an emitter of electromagnetic radiation, a photodetector enabling a detection of electromagnetic radiation of a specific wavelength, a filter having a passband including the specific wavelength, the filter being arranged on the photodetector, the emitter and/or the filter being electrically tunable to the specific wavelength, and a circuit configured to determine a time elapsed between emission and reception of a signal that is emitted by the emitter and then received by the photodetector.
