摘要

Abstract

Temporal cavity solitons are ultrashort optical pulses circulating in driven Kerr resonators. Their intrinsic stability and ability to generate coherent broadband frequency combs have led to breakthroughs in fields such as sensing

metrology

and signal synthesis. However

this robustness limits control over soliton dynamics and constrains comb characteristics. Here

we demonstrate that stationary and moving trapping potentials

generated through intracavity phase modulation

provide unprecedented control over cavity soliton properties. We theoretically show that

for deep potentials

the soliton spectral shift and repetition rate tuning range are primarily limited by a Hopf bifurcation

and reveal the role of dissipation in soliton dynamics. Using a fibre resonator

we observe stable blue- and red-shifted solitons up to 0.4 times their spectral width

at least an order of magnitude larger than with external phase modulation of the drive. We also investigate the interplay between the trapping potential and stimulated Raman scattering

showing that Raman self-frequency shift can be fully compensated

extending the existence range of cavity solitons. Our results provide a new means for stabilising or rapidly tuning the repetition rate of Kerr combs over a wide range

broadening the applications of Kerr frequency combs.
