Query: Soliton dynamics in microresonators with XPM induced negative
  thermo-optic effect   Optical frequency comb generation in microresonators has attracted
significant attention over the past decade, as it offers the promising
potential for chip-scale optical frequency synthesis, optical clocks and
precise optical spectroscopy. However, accessing temporal dissipative Kerr
soliton (DKSs) is known to be severely hampered by thermal effects.
Furthermore, due to the degeneracy of soliton existence range with respect to
soliton number, deterministically accessing single soliton state is another
challenge. Here, we demonstrate stable and deterministic single soliton
generation in AlN-on-sapphire platform via auxiliary laser pumping scheme
without the requirement of fast control of the pump power and detuning.
Moreover, we reveal the underlying physics of soliton switching in a
dual-pumped microcomb, which is fully described by the Lugiato - Lefever
equation. The switching process is attributed to cross-phase modulation (XPM)
induced degeneracy lifting of the soliton existence range, corresponding to an
effective negative thermo-optic effect.
