Modeling of octave-spanning Kerr frequency combs using a generalized mean-field Lugiato-Lefever model.

A generalized Lugiato-Lefever equation is numerically solved with a Newton-Raphson method to model Kerr frequency combs. We obtain excellent agreement with past experiments, even for an octave-spanning comb. Simulations are much faster than with any other technique despite including more modes than ever before.
