Multiple soliton regimes enabled by parametric down-conversion in ${\chi }^{(2)}+{\chi }^{(3)}$ microresonators

Francesco Rinaldo Talenti, Tommi Isoniemi, Jonathan Silver +1

Half-harmonic generation in microresonators with mixed ${\chi }^{(2)}$ and ${\chi }^{(3)}$ nonlinearities provides access to a rich landscape of two-colour soliton states and frequency combs.…
