“…[32] These losses, such as coupling or photon injection losses (1/Qcoupl), can affect the cavity performance in a given application. [84][85][86][87] As a result, numerous approaches for coupling light into optical cavities have been developed with differing degrees of loss. [34,85,86,[88][89][90][91][92][93] Currently, the lowest loss methods are the angle-polished fiber [94], a tapered fiber [95], a coupling prism [96,97], and an integrated bus waveguide [98] (Fig.…”

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.

Efficient nonlinear phenomena in integrated waveguides imply the realization in a nonlinear material of tightly confining waveguides sustaining guided modes with a small effective area with ultra-low propagation losses as well as high-power damage thresholds. However, when the waveguide cross-sectional dimensions keep shrinking, propagation losses and the probability of failure events tend to increase dramatically. In this work, we report both the fabrication and testing of high-confinement, ultralow-loss silicon nitride waveguides and resonators showing average attenuation coefficients as low as ∼3 dB/m across the S-, C-, and L bands for 1.6-µm-width × 800-nm-height dimensions, with intrinsic quality factors approaching ∼10 7 in the C band. The present technology results in very high cross-wafer device performance uniformities, low thermal susceptibility, and high power damage thresholds. In particular, we developed here an optimized fully subtractive process introducing a novel chemical-physical multistep annealing and encapsulation fabrication method, resulting in high quality Si 3 N 4-based photonic integrated circuits for energy-efficient nonlinear photonics and quantum optics.

“…Nonlinear optical interactions acquire qualitatively new features in the strong-coupling regime of cavity quantum electrodynamics (QED), especially when utilizing an extreme field localization achievable in nanophotonic cavities. Even in the standard cavity QED scenario of the strong coupling at the two-wave resonance between only two degrees of freedom, e.g., between an electronic or vibrational transition in a molecule and an electromagnetic (EM) cavity mode, strong coupling has been shown to modify the properties of Raman scattering, generation of harmonics, four-wave mixing, and nonlinear parametric interactions, with applications in photochemistry, quantum information, and quantum sensing; see, e.g., [1][2][3][4][5][6][7][8][9][10][11][12].…”

Many molecular, quantum-dot, and optomechanical nanocavity-QED systems demonstrate strong nonlinear interactions between electrons, photons, and phonon (vibrational) modes. We show that such systems can be described by a universal model in the vicinity of the nonlinear parametric resonance involving all three degrees of freedom. We solve the nonperturbative quantum dynamics in the strong coupling regime of the nonlinear resonance, taking into account quantization, dissipation, and fluctuations of all fields. We find analytic solutions for quantum states in the rotating wave approximation which demonstrate tripartite quantum entanglement once the strong coupling regime is reached. We show how the strong coupling at the nonlinear resonance modifies photon emission and vibrational spectra, and how the observed spectra can be used to extract information about relaxation rates and the nonlinear coupling strength in specific systems.
