  • AN OPTICAL PLURAL-COMB GENERATOR, A METHOD OF GENERATING AN OPTICAL PLURAL COMB, AND A PLURALITY OF MODE LOCKED LASERS THAT ARE MECHANICALLY COUPLED AND OPTICALLY INDEPENDENT
    Publication number: 20200006912
    Abstract: An optical plural-comb generator comprising a plurality of mode-locked lasers that are mechanically coupled and optically independent. The optical plural-comb generator comprises an optical combiner optically coupled to an output of each of the plurality of mode-locked lasers for combining a plurality of optical combs when generated by the plurality of mode-locked lasers.

  • Referencing of the beating spectra of frequency combs
    Patent number: 8625101
    Abstract: There is provided a method for referencing and correcting the beating spectrum generated by the interference of the components of a frequency comb source. The proposed method allows monitoring of variations of a mapping between the source and the beating replica. This can then be used to compensate small variations of the source in Fourier transform spectroscopy or in any other interferometry application in order to overcome the accuracy and measurement time limitations of the prior art. Constraints on source stability are consequently reduced.
