Abstract :
A frequency offset locked loop between two different optical frequency combs spaced from 0.4 THz is reported. In a new experiment, a frequency offset locked loop between one comb and one laser diode as a way to link two combs together is realized. A spacing as wide as 0.6 THz is achieved between the linked combs.
