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 at least one of control the pulsed optical light source (12), control the light receiving unit (14), attenuate the electromagnetic wave packets, phase shift the electromagnetic wave packets, attenuate the electrical signal, and phase shift the electrical signal based on the repeating sequence signal. Moreover, methods for generating an optical frequency comb and for generating an electrical frequency comb are described.
