a Schematic illustration of pattern drift for a soliton. The red curve represents the initial unperturbed soliton, while the blue curves represent the perturbed solitons with pattern drift. b Schematic illustration of pattern deformation for a soliton. The red curve represents the initial unperturbed soliton, while the green curves represent the perturbed solitons with pattern deformation. Pattern drift corresponds to a translational change of the soliton’s azimuthal position within the cavity. On the other hand, pattern deformation corresponds to a change of the soliton’s shape. Our analysis shows that pattern drift is the leading contribution to phase noise at low-frequency offset from the carrier, while pattern deformation is the leading contribution to phase noise at high-frequency offset.
