We build on a previously reported frequency comb of mode spacing 0.136 nm in\na fiber ring cavity of varying normal dispersion [1], to generate, for the\nfirst time, a frequency comb of mode spacing 0.144 nm centered at 978.544 nm to\ndemonstrate the symmetry-breaking. By controlling the birefringence of the\noptical cavity through fiber stretching and polarization control, the spacing\nof the comb lines increases from 0.136 nm to 0.144 nm, and this small change in\nmode spacing generates very different spectral symmetry-breaking in the\nfrequency comb relative to the frequency comb of mode spacing 0.136 nm.\nInterestingly, non-uniform depletion of primary modes is also observed. The\nexperimental results are an important contribution in the continuing effort of\nunderstanding the dynamics of frequency combs involving large number of modes,\nnontrivial nonlinear waves and deterministic chaos.\n
