Query: Soliton linear-wave scattering in a Kerr microresonator   The nonlinear scattering of a linear optical wave from a conservative soliton
has been widely studied in optical fibers as a mechanism for nonlinear
frequency conversion. Here we extend this analysis to consider the scattering
of an externally injected probe wave from a dissipative Kerr cavity soliton
circulating in a Kerr microresonator. We demonstrate, both theoretically and
experimentally, that this nonlinear interaction can be harnessed for useful
expansion of the soliton frequency comb via the formation of a secondary idler
comb. We explore the physics of the process, showing that the phase detuning of
the injected probe from a cavity resonance plays a key role in setting the
central frequency of the idler comb, thus providing a convenient parameter
through which to control the spectral envelope of that comb. Our results
elucidate the dynamics that govern the interactions between dissipative Kerr
cavity solitons and externally injected probe waves, and could prove useful in
the design of future Kerr frequency comb systems by enabling the possibility to
provide high-power comb lines in a specified spectral region simply through the
injection of a suitably chosen probe.
