Article Abstract
In this work, we report on manipulating the polarization characteristics of temporal solitons in a microfiber Fabry-Pérot (FP) laser with a fundamental repetition rate of 20 GHz at 1.5 μm. By controlling the temperature of the microfiber oscillator, the state of temporal solitons can be switched from vector to scalar (linearly polarized) state. Further experimental and numerical studies suggest that polarization dynamics of temporal solitons are related to cavity birefringence changes in thermal manipulation, i.e., polarization-evolution frequency of vector solitons is reduced with weakened birefringence. Finally, the 20-GHz fiber laser, operating at scalar state, exhibits a radio frequency signal with a signal-to-noise ratio of >80 dB. These efforts may provide a flexible method for controlling micro fiber FP lasers.

Time crystals are unexpected states of matter that spontaneously break time-translation symmetry either in a discrete or continuous manner. However, spatially mesoscale space-time crystals that break both space and time symmetries have not been reported. Here we report a continuous space-time crystal in a nematic liquid crystal driven by ambient-power, constant-intensity unstructured light.

We report on numerical predictions and experimental observations of a novel type of temporal localized dissipative structures that manifest themselves in the self-defocusing regime of driven nonlinear optical resonators with two polarization modes. These chiral dissipative solitons, which we term "polarization faticons," break both temporal and polarization symmetry and consist of two bright lobes of opposite polarization handedness, interlocked by a domain wall. Our study reveals that faticons are connected to a vectorial modulational instability, from which they can be excited through a collapsing dynamic.

The oblique collisions and dynamical interference patterns of two-dimensional dispersive shock waves are studied numerically and analytically via the temporal dynamics induced by wedge-shaped initial conditions for the Kadomtsev-Petviashvili II equation. Various asymptotic wave patterns are identified, classified, and characterized in terms of the incidence angle and the amplitude of the initial step, which can give rise to either subcritical or supercritical configurations, including the generalization to dispersive shock waves of the Mach reflection and expansion of viscous shocks and line solitons. An eightfold amplification of the amplitude of an obliquely incident flow upon a wall at the critical angle is demonstrated.

However, few efforts have been devoted to investigating the nonlinear dynamics of DPQS. Herein, we numerically investigate the pulsating dynamics of the DPQS in a passively mode-locked fiber laser.
