“…Our results are in excellent agreement with numerical simulations that take naturally into account the linear coupling between the dominant transverse modes of the microresonator. Strikingly, we find that the formation of dark-pulse Kerr combs is also accompanied by the appearance of an extra resonance, in compelling similarity to the behavior reported for DKS 14 and perfect soliton crystals 13 . In contrast, however, our measurements reveal that in dark-pulse Kerr combs, the pump is effectively blue-detuned with respect to the cavity resonance that is Kerr shifted due to the high power CW background of the dark-pulse.…”

Dissipative Kerr solitons are localized structures that exist in optical microresonators. They lead to the formation of microcombs -chip-scale frequency combs that could facilitate precision frequency synthesis and metrology by capitalizing on advances in silicon photonics.Previous demonstrations have mainly focused on anomalous dispersion microresonators.Notwithstanding, localized structures also exist in the normal dispersion regime in the form of circulating dark pulses, but their physical dynamics is far from being understood. Here, we report the discovery of reversible switching between coherent dark-pulse Kerr combs, whereby distinct states can be accessed deterministically. Furthermore, we reveal that the formation of dark-pulse Kerr combs is associated with the appearance of a new resonance, 1 arXiv:1910.11035v1 [physics.optics]

“…The challenge of theoretically or experimentally finding the optimal route has impeded the implementation of this proposal. On the other hand, it has been demonstrated that reverting the pump frequency tuning direction will provide a simpler route to stable single solitons [238].…”

The experimental realization of a Kerr frequency comb represented the convergence of research in materials, physics, and engineering, and this symbiotic relationship continues to underpin efforts in comb innovation today. While the initial focus developing cavity-based frequency combs relied on existing microresonator architectures and classic optical materials, in recent years, this trend has been disrupted. This paper reviews the latest achievements in frequency comb generation using resonant cavities, placing them within the broader historical context of the field. After presenting well-established material systems and device designs, the emerging materials and device architectures are examined. Specifically, the unconventional material systems as well as atypical device designs that have enabled tailored dispersion profiles and improved comb performance are compared to the current state of art. The remaining challenges and future outlook for the field of cavity-based frequency combs is evaluated.

“…We obtained a multi-soliton comb by directly tuning the pump laser wavelength from the blue to the red side of the resonance, and monitored the comb power as shown in Fig.3 (d). Then, the backward tuning method [31] was used to achieve a single soliton comb which is shown in Fig.3 (c). The obtained soliton comb covers a spectrum from 1300 nm to 2200 nm with a clear dispersive wave generated at 2100 nm [32].…”

High-Q Si₃N₄ microresonators based on a subtractive processing for Kerr nonlinear optics

Microresonator frequency combs (microcombs) are enabling new applications in frequency synthesis and metrologyfrom high-speed laser ranging to coherent optical communications. One critical parameter that dictates the performance of the microcomb is the optical quality factor (Q) of the microresonator. Microresonators fabricated in planar structures such as silicon nitride (Si3N4) allow for dispersion engineering and the possibility to monolithically integrate the microcomb with other photonic devices. However, the relatively large refractive index contrast and the tight optical confinement required for dispersion engineering make it challenging to attain Si3N4 microresonators with Qs > 10 7 using standard subtractive processing methodsi.e. photonic devices are patterned directly on the asdeposited Si3N4 film. In this work, we achieve ultra-smooth Si3N4 microresonators featuring mean intrinsic Qs around 11 million. The cross-section geometry can be precisely engineered in the telecommunications band to achieve either normal or anomalous dispersion, and we demonstrate the generation of mode-locked dark-pulse Kerr combs as well as soliton microcombs. Such high-Qs allow us to generate soliton microcombs with photodetectable repetition rates, demonstrated here for the first time in Si3N4 microresonators fabricated using a subtractive processing method. These results enhance the possibilities for co-integration of microcombs with high-performance photonic devices, such as narrow-linewidth externalcavity diode lasers, ultra-narrow filters and demultiplexers.
