Beschreibung
Zusammenfassung:	A frequency comb generating device (10) is described. The frequency comb generating device (10) comprises a pulsed optical light source (12), a sequence generator (16), a light receiving unit (14) and a switching unit (18). The sequence generator (16) is configured to generate a repeating sequence signal and to forward the repeating sequence signal at least to the switching unit (18). The pulsed optical light source (12) is configured to generate electromagnetic wave packets and is synchronized with the sequence generator (16). The light receiving unit (14) is configured to receive the electromagnetic wave packets and to convert the electromagnetic wave packets into an electrical signal. The switching unit (18) is configured to attenuate the electromagnetic wave packets based on a current value of the repeating sequence signal. The switching unit (18) is an optical switch connected to the light receiving unit (14), the switching unit (18) being positioned upstream of the light receiving unit (14). The switching unit (18) is configured to cancel out an electromagnetic wave packet for at least one value and to not alter the electromagnetic wave packets for the other values.
