Bistable soliton optical frequency combs in a second harmonic generation Kerr cavity
Francesco Rinaldo Talenti, Stefan Wabnitz, Yifan Sun +8
We study the dynamics and stability of soliton optical frequency comb generation in a dissipative, coherently pumped cavity with both second and third-order nonlinearity. Cavity sw…
