Dr Chris Perrella Summarises an Applied Physics B Paper on Frequency combs
Interferometric selection of frequency comb modes
We split an optical frequency comb into four separate 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 actively stabilized fiber interferometers. 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.
