  How does the behavior of front solutions differ between high and low drive powers in a normal dispersion Kerr resonator without spectral filtering?	Here, we develop some insight into the difference between dark solitons in the LLE and LLE-F as well as into the formation of chirped-pulse solitons unique to the LLE-F. For fixed detuning, Fig. 7 indicates that the drive power is a suitable parameter for traversing between the different solution types. We therefore examine the variation of steady-state solutions along the dashed line in Fig. 7. For a normal dispersion Kerr resonator without spectral filtering, front solutions (also known as domain walls or switching waves) often move in the reference frame of the driving field [19,54,55,66]. To examine the moving properties of front solutions, we initialize the simulation with a two-front intensity variation in the time domain. The equation is numerically solved with this initial condition and examined as a function of propagation distance until the waveform converges. At large drive powers without a filter [Fig. 8(a) and a from Fig. 7], the front solutions move together and vanish to...	Dissipative solitons are self-localised structures resulting from the double balance of dispersion by nonlinearity and dissipation by a driving force arising in numerous systems. In Kerr-nonlinear optical resonators, temporal solitons permit the formation of light pulses in the cavity and the generation of coherent optical frequency combs. Apart from shape-invariant stationary solitons, these systems can support breathing dissipative solitons exhibiting a periodic oscillatory behaviour. Here, we generate and study single and multiple breathing solitons in coherently driven microresonators. We present a deterministic route to induce soliton breathing, allowing a detailed exploration of the breathing dynamics in two microresonator platforms. We measure the relation between the breathing frequency and two control parameters--pump laser power and effective-detuning--and observe transitions to higher periodicity, irregular oscillations and switching, in agreement with numerical predictions....
  What are the key advantages of microcombs that make them suitable for portable applications?	Microresonator based optical frequency comb (often termed "microcomb" or "Kerr comb) generation was first demonstrated in 2007 [1]. It quickly attracted people's great interest and evolved to a hot research area. Microcombs are very promising for portable applications because they have many unique advantages including the capability of generating ultra-broad comb spectra (even more than one octave [2,3]), chip-level integration [4,5], and low power consumption. The basic scheme of microcomb generation is shown in Fig. 1(a). The frequency of a pump laser is tuned into the resonance of one high-quality-factor $(\boldsymbol{Q})$ microresonator which is made of Kerr nonlinear material. When the pump power exceeds some threshold, new frequency lines grow due to parametric gain. More lines are generated through cascaded four-wave mixing between the pump and initial lines, forming a broad frequency comb [6]. Intense studies have been performed to investigate microcomb generation. Various mate...	We briefly review the physics of the parametric process in microresonators, discussed in detail in (30, 80). Kerr frequency combs were initially discovered in silica microtoroids, and experiments proved that the parametrically generated (11, 81) sidebands were equidistant to at least one part in $10^{-17}$ as compared with the optical carrier. In these early experiments, the combs repetition rate was in the terahertz range, and a femtosecond-laser frequency comb was used to bridge and verify the equidistant nature of the teeth spacing. It is today understood that such highly coherent combs only exist in certain regimes.
  What is the formula for determining the number of rolls that appear in the azimuthal direction when the cavity is pumped just above the threshold of modulational instability?	Roll patterns emerge from noise after the breakdown of an unstable flat background through modulational instability, when the resonator is pumped above a certain threshold. This mechanism preferably occurs in the regime of anomalous GVD, but, however, rolls can also be sustained in the normal GVD regime, although under very marginal conditions (typically, very large detuning, see refs. [9, 18, 47]). [object Object]When the pump is below the threshold, there is only one excited mode in the resonator $\left(l\ =\ 0\right)$ , while all the sidemodes amplitudes $\mathcal{A}[object Object]{\mathrm{th}}$ , the flat background solution becomes unstable and breaks down into a roll pattern characterized by a periodic modulation of the intracavity power as a function of the azimuthal angle (see Fig. 6). This phenome...	$$ [object Object]Note that $\mathcal{N}[object Object]{h}S^{-1}$ and $\mathcal{I N}[object Object]{h}S^{-1}$ , so the spectra of the full linearized operator, $\mathcal{I N}[object Object]{h}$ . Also, $\sigma(\mathcal{N}[object Object]{h})$ [object Object]Since the two problems are equivalent, we note that the form (4.3) of the eigenvalue problem is more suggestive of our approach. For $h=0$ , we have two dimensional $\mathrm{Ker}[\mathcal{M}[object Object]{0}^{\prime}}\ {0}\end{array}\big)$ and $\big(\begin{array}{c}{0}\ {\varphi_{0}}\end{array}\big)$ . We need to see what the evolution of the modulational eigenvalue is as $h:0<h<<1$ , i.e., the one corresponding to the eigenvector $\big(\begin{array}{c}{0}\ {\varphi_{0}}\end{array}\big)$ . This is because, by index counting theory, the instability can only appear in the even subspace of the problem. Also, we can clearly consider $\mathcal{M}_...
