a. Top: eigenvalue solution of the quadrature Hamiltonian \({\mathcal{M}}\) for a 2-FSR Kerr comb with side band drop ratio of \({\mathcal{R}}=2.25\), and D2/2π = 1.2MHz. Bottom: Zoom-in on the quadrature supermodes with higher-gain showing that all of them are undetuned (imaginary value is 0.) b. Same as a. only with \({D}_{1}^{{\prime} }/2\pi =2.8\,MHz\). c.,d. Numerically counting the un-detuned states as a function of underlying GVD (D2) and detuning of the comb for the symmetric case of \({D}_{1}^{{\prime} }=0\) and the non-symmetric case \({D}_{1}^{{\prime} }/2\pi =2.8\,MHz\).
