Noise-induced synchronization is known in classical systems and has recently been proposed in quantum many-body settings. Here, the authors experimentally demonstrate stable and entangled synchronized oscillations at the ends of a superconducting qubit chain by applying Gaussian noise to a single qubit.

Stable and tunable integrated lasers are fundamental building blocks for applications from spectroscopy to imaging and communication. Here the authors present a narrow linewidth hybrid photonic integrated laser with low frequency noise and fast linear wavelength tuning. They then provide an efficient FMCW LIDAR demonstration.

Here, the authors generate dissipative Kerr solitons with stable repetition rates and low optical power threshold. They achieve this by actively switching the bias current of injection-locked III-V semiconductor lasers and pulse-pumping crystalline and integrated microresonators with picosecond laser pulses.

’Here the authors provide the demonstration of platicon comb generation in an integrated photonic chip using laser self-injection locking, They take advantage of platicons generation in normal GVD resonators, which significantly relaxes the material and geometry design restrictions

Molecules of solitons provide insight into fundamental interactions between them and the underlying nonlinear system. The reported heteronuclear molecules, comprised of dissipative solitons with distinct frequencies, temporal widths, and energies enter the multistability regime and yield in interlocked frequency combs.

Here, the authors find the missing link for soliton microcombs that exist at the boundary where the group velocity dispersion of light changes sign: zero-dispersion solitons. The resulting microresonator frequency comb, based in Si3N4, spans almost an octave.

Self-injection locking of the pump laser for a soliton microcomb has significantly relaxed the requirements for laser drives. Here the authors study self-injection locking in experiment and theory and reveal that the soliton formation is feasible with detunings unreachable according to previous theories.

By monolithically integrating piezoelectric actuators on ultralow-loss photonic circuits, soliton microcombs—a spectrum of sharp lines over a range of optical frequencies—can be modulated at high speeds with megahertz bandwidths.

A dissipative Kerr soliton crystal state is a temporally ordered regular ensemble of soliton pulses within a cavity. Chaotic driving of optical resonators enables the defect-free creation and dynamical characterization of these states.

The direct generation of mid-infrared optical frequency combs in the region 2.5–4.0 μm from a 1.55-μm conventional and compact erbium-fibre-based femtosecond laser is demonstrated via coherent dispersive wave generation in silicon nitride nanophotonic waveguides.

A massively parallel coherent light detection and ranging (lidar) scheme using a soliton microcomb—a light source that emits a wide spectrum of sharp lines with equally spaced frequencies—is described.
