We reveal the generation of a broadband (> 1.9 THz) bi-photon quantum frequency comb (QFC) in a silicon-on-insulator (SOI) Fabry–Pérot micro-cavity and the control of its spectral correlation properties. Correlated photon pairs are generated through three spontaneous four-wave mixing (SFWM) processes by using a co-polarized bi-chromatic coherent input with power P₁ and P₂ on adjacent resonances of the nonlinear cavity. Adjusting the spectral power ratio r = P₁/(P₁ + P₂) allows control over the influence of each process leading to an enhancement of the overall photon pair generation rate (PGR) μ(r) by a maximal factor of μ(r = 0.5)/μ(r = 0) ≈ 1.5, compared to the overall PGR provided by a single-pump configuration with the same power budget. We demonstrate that the efficiency a _ND of the non-degenerate excitation SFWM process (NDP) doubles the efficiency a₁ ≈ a₂ of the degenerate excitation SFWM processes (DP), showing a good agreement with the provided model.
