“…Microresonator-based Kerr frequency combs have attracted intense interest for their promising applications in many fields, including astronomical spectrograph calibration, high-precision frequency-comb spectroscopy, and telecommunication systems [1][2][3][4]. Such chip-level integratable microcavities with a high quality factor enable efficient nonlinear optical processes like cascaded four-wave mixing (FWM), which can lead to broadband frequency-comb generation from a continuous-wave laser.…”

We investigate frequency-comb generation in normal dispersion silicon microresonators from the near-infrared to mid-infrared wavelength range in the presence of multiphoton absorption and free-carrier effects. It is found that parametric oscillation is inhibited in the telecom wavelength range resulting from strong two-photon absorption. On the contrary, beyond the wavelength of 2200 nm, where three-and four-photon absorption are less detrimental, a comb can be generated with moderate pump power, or free-carriers are swept out by a positive-intrinsic-negative structure. In the temporal domain, the generated combs correspond to flat-top pulses, and the pulse duration can be easily controlled by varying the laser detuning. The reported comb generation process shows a high conversion efficiency compared with anomalous dispersion regime, which can guide and promote comb formation in materials with normal dispersion. As the comb spectra cover the mid-infrared wavelength range, they can find applications in comb-based radiofrequency photonic filters and mid-infrared spectroscopy.

“…DKSs in microresonators have provided a route to compact low power in chipfrequency comb generation. Although Kerr combs have been known for more than one decade (7) [and have been reviewed in (6,(26)(27)(28)], the discovery of the DKS regime (9) has unlocked their full potential by providing a route to broadband and fully coherent microresonator-based frequency combs, overcoming earlier challenges of low coherence (29)(30)(31). Such soliton-based microcombs in chip-integrated microresonators have achieved low-power, octave-spanning frequency combs in various spectral windows that now encompass the near-infrared (32,33), telecommunication (34,35), and mid-infrared spectral window (18,36), with repetition rates from only a few gigahertz (37) to terahertz.…”

The development of compact, chip-scale optical frequency comb sources (microcombs) based on parametric frequency conversion in microresonators has seen applications in terabit optical coherent communications, atomic clocks, ultrafast distance measurements, dual-comb spectroscopy, and the calibration of astophysical spectrometers and have enabled the creation of photonic-chip integrated frequency synthesizers. Underlying these recent advances has been the observation of temporal dissipative Kerr solitons in microresonators, which represent self-enforcing, stationary, and localized solutions of a damped, driven, and detuned nonlinear Schrödinger equation, which was first introduced to describe spatial self-organization phenomena. The generation of dissipative Kerr solitons provide a mechanism by which coherent optical combs with bandwidth exceeding one octave can be synthesized and have given rise to a host of phenomena, such as the Stokes soliton, soliton crystals, soliton switching, or dispersive waves. Soliton microcombs are compact, are compatible with wafer-scale processing, operate at low power, can operate with gigahertz to terahertz line spacing, and can enable the implementation of frequency combs in remote and mobile environments outside the laboratory environment, on Earth, airborne, or in outer space.

“…Within a few decades, optical Kerr-nonlinear resonators have emerged as the paradigmatic setup for the study of externally driven nonlinear systems [7][8][9]. With length scales ranging from the meter to micrometer [10,11], their applications range from high-demand telecommunications [12] to precision spectroscopy and LIDAR (Light Detection And Ranging) systems [13] based on the coherent optical frequency * saliya.coulibaly@univ-lille.fr combs that can be delivered. Kerr resonators are also known for the property to continuously switch between a monostable (single-valued transmission curve) and bistable (S-shape transmission curve) regimes.…”

Turbulence-Induced Rogue Waves in Kerr Resonators

et al. 2019

Spontaneous emergence of self-organized patterns and their bifurcations towards a regime of complex dynamics in non-equilibrium dissipative systems is a paradigm of phase transition. Indeed, the behavior of these patterns in the highly nonlinear regime remains less explored, even in recent high-quality-factor resonators such as Kerr-nonlinear optical ones. Here, we investigate theoretically and experimentally the alteration of the resulting Kerr frequency combs from the weakly to the highly nonlinear regime, in the frameworks of spatiotemporal chaos, and dissipative phase transitions. We reveal the existence of a striking and easily accessible scenario of spatiotemporal chaos, free of cavity solitons, in a monostable operating regime, wherein a transition to amplitude turbulence via spatiotemporal intermittency is evidenced. Moreover, statistics of the light bursts in the resulting turbulent regime unveils the existence of rogue waves as extreme events characterized by long-tail statistics.
