Query: Soliton regulation in microcavities induced by
  fundamental-second-harmonic mode coupling   Microcomb generation with simultaneous $\chi^{(2)}$ and $\chi^{(3)}$
nonlinearities brings new possibilities for ultra-broadband and potentially
self-referenced integrated comb sources. However, the evolution of the
intracavity field involving multiple nonlinear processes shows complex dynamics
that is still poorly understood. Here we report on strong soliton regulation
induced by fundamental-second-harmonic (FD-SH) mode coupling. The formation of
solitons from chaos is extensively investigated based on coupled
Lugiato-Lefever equations. The soliton generation shows more deterministic
behaviors in the presence of FD-SH mode interaction, in sharp contrast to the
usual cases where the soliton number and relative locations are stochastic.
Deterministic single soliton transition, soliton binding and prohibition are
observed, depending on the phase matching condition and coupling coefficient
between the fundamental and second-harmonic waves. Our finding provides
important new insights into the soliton dynamics in microcavities with
simultaneous $\chi^{(2)}$ and $\chi^{(3)}$ nonlinearities, and can be immediate
guidance for broadband soliton comb generation with such platforms.
