Abstract
We demonstrate a scheme to split an optical frequency comb into four separate frequency combs, each with four times the repetition rate of the original, but which are offset in frequency from each other. These spectrally rarified "daughter" combs are generated using fibre interferometers that are actively stabilised. We describe how these "daughter" combs can be used to resolve ambiguities that occur when comparing an arbitrary frequency continuous-wave signal against an optical frequency comb. © 2013 Springer-Verlag Berlin Heidelberg.
