“…Soliton breather states in the damped and driven nonlinear Schrödinger (Lugiato-Lefever) equation have been known for a long time [13,14]. The recent resurgence in studies of their properties has happened primarily through the context of the frequency comb generation in microresonators [8][9][10][11][15][16][17][18][19][20]. What was particularly interesting for us to find and report here is Fig.…”

“…Comb self-referencing requires achieving the octave-wide soliton spectral spans. Methods to generate the broad soliton combs rely on, e.g., reducing the microresonator radius [3,4], higher order dispersion [5,6], frequency doubling in a material with 𝜒 (2) nonlinearity [7] and bi-chromatic pump [8][9][10].…”

“…However, this ideal grid does not always extend across the entire comb. The spectral structure of the octave combs should be carefully examined on a case-by-case basis because it can be composed of the overlapping combs having different repetition rates and different carrier-envelope offset frequencies [8][9][10][11]. For the sake of brevity, we refer below to the carrier-envelope offset frequencies as the offset frequencies or offsets.…”

Octave-wide frequency combs in microresonators are essential for self-referencing. However, it is difficult for the small-size and high-repetition-rate microresonators to achieve perfect soliton modelocking over the broad frequency range due to the detrimental impact of dispersion. Here we examine the stability of the soliton states consisting of one hundred modes in silicon-nitride microresonators with the one-THz free spectral range. We report the coexistence of fast and slow solitons in a narrow detuning range, which is surrounded on either side by the breather states. We decompose the breather combs into a sequence of sub-combs with different carrier-envelope offset frequencies. The large detuning breathers have a high frequency of oscillations associated with the perturbation extending across the whole microresonator. The small detuning breathers create oscillations localised on the soliton core and can undergo the period-doubling bifurcation, which triggers a sequence of intense sub-combs.

“…In a system with a single pump, the rotation velocity of the soliton is largely determined by the primary pump, but in a system with a secondary pump that has a different unperturbed rotation velocity, the secondary pump pulls the rotation velocity, so that the resulting soliton rotation velocity is a combination of the two rotation velocities [43]. This effect becomes large when the secondary pump has nearly the same magnitude as the main pump, which is the case in recent experiments [12,44].…”

Dissipative Kerr solitons (DKSs) in optical microresonators have been intensely studied from the perspective of both fundamental nonlinear physics and portable and low power technological applications in communications, sensing, and metrology. In parallel, synthetic dimensions offer the promise of studying physical phenomena with a dimensionality beyond that imposed by geometry, and have been implemented in optics. The interplay of DKS physics with synthetic dimensions promises to unveil numerous new physical and technological insights, yet many fundamental challenges remain. In particular, DKSs intrinsically rely on dispersion to exist while the creation of synthetic frequency lattices typically needs a dispersion-less system. We present a change of paradigm with the creation of a synthetic frequency lattice in the eigenfrequency space of a dispersive multi-color soliton through all-optical nonlinear coupling -compatible with octave spanning microcombsharnessing the interplay between the cavity dispersion and the dispersion-less nature of the DKS. We examine theoretically and experimentally the nonlinear coupling mechanism in a 1 THz repetition rate resonator and demonstrate four-wave mixing Bragg scattering between the different wavepackets forming the multi-color soliton, with the microcomb ranging over 150 THz, yielding a complex all-optical and integrated synthetic frequency lattice.

Nonlinear Scattering of Dissipative Solitons in a Kerr Microresonator

Abstract: We show that nonlinear scattering between a linear wave and a soliton in a Kerr microresonator generates an idler comb at a frequency determined by the linear wave detuning, allowing for spectral manipulation of the soliton comb.
