  • Microresonator frequency combs are versatile tools for sensing, data transmission and quantum applications. In this work the authors present the generation of low-noise frequency combs at repetition rates of 100 GHz by utilizing a cascaded forward-propagating Brillouin scattering process to seed soliton frequency comb generation.

  • The nonlinear dynamic interaction between optical comb frequencies and microresonator modes are not yet fully understood. Here, the authors demonstrate a method to characterize microcomb states and observe discrete phase steps that have not been observed in conventional frequency combs.

  • The observation of soliton crystals in monolithic Kerr microresonators is reported. The physics of such resonators is explored in a regime of dense soliton occupation, offering a way to increase the efficiency of Kerr combs.

  • Direct f–2f self-referencing of a microresonator-based optical frequency comb is demonstrated at a repetition rate of 16.4 GHz. The carrier envelope offset frequency and repetition rate are stabilized to a hydrogen maser-based atomic clock.

  • Amplification of laser pulses is key for ultrafast and broadband measurements in physics, biology, and chemistry. Here, the authors show that a femtosecond pulse amplifier, providing 800 Watts of peak power, can be integrated on a photonic chip.

  • Broadband frequency combs are a key enabling technology for frequency metrology and spectroscopy. Here, the authors demonstrate that the spectrum of a soliton microcomb can be extended by bichromatic pumping resulting in two combs that synchronize their repetition rate via cross-phase modulation.

  • 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.
