  • Coherent Ising machines suffer from stringent phase stabilization requirements. Here, authors provide a proof-of-concept demonstration of an optical coherent Ising machine, where spins are encoded in the polarization of light and can be accessed via intensity measurements, thereby lifting the limitations related to phase stabilization.

  • Slow nonlinearities of a free-running microresonator-filtered fibre laser are shown to transform temporal cavity solitons into the system’s dominant attractor, leading to reliable self-starting oscillation of microcavity-solitons that are naturally robust to perturbations.

  • Applications of spontaneous symmetry breaking are hindered by unavoidable imperfections. Here, the authors reveal how a phase defect provides topological robustness to this process, enabling a bias free realization without fine tuning of parameters.

  • Dissipative solitons and their symmetry breaking is important for photonic applications. Here the authors show that dissipative solitons can undergo spontaneous symmetry breaking in a two-component nonlinear optical ring resonator, resulting in the coexistence of distinct vectorial solitons with asymmetric, mirror-like states of polarization.

  • By nesting a Kerr microresonator in a fibre loop with gain, 50-nm-wide bright microcavity-based soliton combs with a mode efficiency of 75% can be induced at average powers more than one order of magnitude lower than the Lugiato–Lefever soliton power threshold, facilitating real-world applications.

  • There has been great success in observing the spontaneous symmetry breaking (SSB) of temporal cavity solitons (TCS) in Kerr ring resonators, but similar phenomena in linear Fabry-Pérot cavities are still unexplored. The authors establish the field polarization properties for the SSB of TCS, and characterize the SSB in a model Fabry-Perot resonator.

  • Spontaneous symmetry breaking of light in ring resonators are of broad interest due to its fundamental properties in nonlinear optics and its potential applications in photonic circuits and optical communications. This work reports the multi-stage symmetry breaking in ring resonators with Kerr nonlinearity, which can find applications such as photonic isolators and circulators, logic gates, and random number generators.
