“…This dependence motivated recent research into developing motorized or automated mechanical polishing methods. [341] Second, it is necessary to have low loss photon injection to achieve high performing combs. To meet this criterion, low loss couplers, such as prisms or tapered fibers, are used.…”

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 review recent trends in the generation of a frequency comb in a microresonator, which is also known as a microcomb. The review includes both its history and applications. We explain on the basics in relation to how phase-locked and soliton states are achieved. Then, issues such as the coupling with optomechanics are discussed, which reveal the rich physics involved in this system. Finally, we describe how to extend the comb generation bandwidth by using stimulated Raman scattering and third harmonic generation.
