Color Symmetry Breaking in a Nonlinear Optical Microresonator

open access: yesLaser &Photonics Reviews, EarlyView.
A two‐color pump drives an integrated microring resonator into spontaneous color symmetry breaking mediated by the nonlinear Kerr effect. Above threshold, one optical color becomes spontaneously dominant while the other is submissive, with the selected output state emerging randomly. These results establish a new form of symmetry breaking in integrated

Real‐Time Observation of Soliton Buildup and Self‐Organization in a GHz Harmonic Mode Locked Fiber Laser

open access: yesLaser &Photonics Reviews, EarlyView.
This image is an experimental recording of the buildup of harmonic mode‐locking in a fiber laser. The horizontal dimension corresponds to one cavity round trip, where the laser field intensity is displayed in a color scale. The vertical dimension is the evolution time in logarithmic scale, spanning from microseconds to seconds.

Non-self-dual nontopological soliton in a pure Chern–Simons gauge model

open access: yesEuropean Physical Journal C: Particles and Fields
A nontopological soliton of the Q-ball type in a Chern–Simons–Higgs gauge model is studied using both analytical and numerical methods. The general non-self-dual case is considered.

Vortex-stripe soliton interactions

open access: yesOptics Letters, 2000
We study the interaction of an optical vortex soliton with a dark-soliton stripe in a bulk nonlinear defocusing medium. We develop a multiscale asymptotic theory to predict the main effect of the interaction and then study it experimentally, observing vortex-induced stripe bending, development of the transverse instability, and stripe breakup.

Unveiling New Perspectives on the Hirota–Maccari System With Multiplicative White Noise

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT In this study, we delve into the stochastic Hirota–Maccari system, which is subjected to multiplicative noise according to the Itô sense. The stochastic Hirota–Maccari system is significant for its ability to accurately model how stochastic affects nonlinear wave propagation, providing valuable insights into complex systems like fluid dynamics

Interferometric Vector Piezoresponse Force Microscopy for Simultaneous Ferroelectric Domain and Crystallographic Orientation Mapping in Uniaxial Ferroelectric Polycrystals

open access: yesSmall, EarlyView.
Interferometric vector piezoresponse force microscopy is used to reconstruct crystallographic grain orientations in polycrystalline ferroelectrics directly from local electromechanical response. The approach reveals grain orientation, polarization direction, and domain structure simultaneously, establishing a pathway toward EBSD‐like orientation ...
