Frequency combs have found tremendous utility as precision instruments. Although the distribution of noise across a comb has been investigated, the role of correlations among various frequencies has yet to be explored. Here we demonstrate the presence of strong anti-correlations among two spectral portions of a standard monolithic Fabry-Perot QCL that operates in the comb regime.
