Dirac Solitons in Optical Microresonators (FTu4E.1)
Presenter: Heming Wang, California Institute of Technology

We demonstrate optical Dirac solitons in microresonators by polarization mode coupling. The solitons show unusual properties such as polarization twisting and asymmetrical spectra, and they provide a road-map for visible-band soliton generation in microresonators.

  Paper

Nonlinear Optical Response of Metal-Dielectric Nanocavities Resonating in the Near-Infrared (FTu4E.2)
Presenter: Nicolò Maccaferri, University of Luxembourg

We study the nonlinear emission of single metal-dielectric nanostructures resonating in the near-infrared. We achieve one order of magnitude higher second-harmonic generation efficiency compared to gold nanostructures with the same geometry and resonant behavior.

Dark-Pulse Dynamics and Directional Switching in Photonic-Crystal Ring Resonators (FTu4E.3)
Presenter: Erwan Lucas, National Institute of Standards and Technology

Microcomb generation under normal dispersion requires an external phase-matching condition, which we fulfill with a photonic crystal (PhC) in a ring resonator. The bidirectional coupling induced by the PhC leads to a non-trivial direction of propagation and breathing of the nonlinear pulse state.

Symmetry Protection Against Mode Crossings in Multimode Photonic Resonator Chains (FTu4E.4)
Presenter: Alexey Tikan, Institute of Physics, Swiss Federal Institute of Technology Lausanne (EPFL)

The accessibility of solitons in driven-dissipative photonic dimers drastically varies for different supermode families. We explain the origin of this phenomenon and show its crucial influence on any soliton lattice configuration including topological arrangements.

Tunable Kerr Combs in a Normal Dispersion Pulse-Driven Mini-Resonator (FTu4E.5)
Presenter: Stuart Murdoch, University of Auckland

Kerr combs are demonstrated in a purely normal dispersion pulse-driven fiber mini-resonator. Though harmonic driving and tunable desynchronization, we are able to control both the spectral extents and line spacing of the output comb.

Soliton Slingshot in Over-Moded Microresonators (FTu4E.6)
Presenter: Teng Tan, University of Electronic Science & Technology of China

Leveraging the avoid mode couplings in microsphere resonators, we demonstrated fast soliton slingshot intracavity. Its soliton access range reaches 8 GHz, with success possibility > 90% and single soliton ratio > 60%.

  Paper

Dark- and Bright-Pulse States in Photonic Crystal Ring Resonators (FTu4E.7)
Presenter: Su-Peng Yu, National Inst of Standards & Technology

Kerr microresonators with normal dispersion support dark- and bright-pulse states, characterized by either locally vanishing or enhanced intensity. We demonstrate that exciting the photonic-crystal resonator defect mode enables continuous tuning between dark and bright solitons.
