Abstract :
An algorithm for self-referenced spectral magnitude and phase retrieval of both optical frequency combs from a dual-comb multiheterodyne interferogram is rigorously defined. The algorithm is generalized to allow for the repetition rates of the two combs to be significantly different which allows for a reduction in required RF bandwidth. The validity of the algorithm is confirmed with an experimental demonstration.
