Enhanced Nonlinear Optical Absorption Properties and Carrier Dynamics of Violet Phosphorene by Oxidation for Ultrafast Photonic Applications

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study investigates the effects of oxidation treatment on the nonlinear optical absorption properties and carrier dynamics of two‐dimensional violet phosphorene (VP), elucidating the underlying physical mechanisms. Furthermore, ultrashort laser pulses are achieved utilizing the enhanced saturation absorption and shortened carrier relaxation ...

Topological dragging of solitons

, 2005
We put forward properties of solitons supported by optical lattices featuring topological dislocations, and show that solitons experience attractive and repulsive forces around the dislocations.

Dynamics and stability of Bose-Einstein solitons in tilted optical lattices [PDF]

, 2010
Bloch oscillations of Bose-Einstein condensates realize sensitive matter-wave interferometers. We investigate the dynamics and stability of bright-soliton wave packets in one-dimensional tilted optical lattices with a modulated mean-field interaction $g ...

Temperature‐robust exchange bias and spin‐orbit torque switching in van der Waals heterostructure

InfoMat, EarlyView.
Exchange bias (EB) in ferromagnetic/antiferromagnetic materials enables high‐density spintronic devices. A Fe3GaTe2/NiPS3 heterostructure exhibits EB up to 150 K, with spin orbit torque switching observed in both stacking orders. Interface layer effects induce net magnetism and magnetization flipping via Fe3GaTe2 domains, with strong interlayer ...

Partially incoherent gap solitons in Bose-Einstein condensates

, 2006
We construct families of incoherent matter-wave solitons in a repulsive degenerate Bose gas trapped in an optical lattice (OL), i.e., gap solitons, and investigate their stability at zero and finite temperature, using the Hartree-Fock-Bogoliubov ...

Dispersion‐Less Dissipative Soliton Fiber Laser

Laser &Photonics Reviews, EarlyView.
A dispersion‐less fiber laser architecture generates high‐energy, pedestal‐free picosecond pulses without resorting to conventional pulse stretching. This energy‐managed laser achieves remarkable flexibility in pulse parameters, delivering up to 0.54 μJ$\mathrm{\mu}\mathrm{J}$ pulses with minimal spectral distortion using standard telecom components ...

Interaction of vector solitons with a nonlinear interface

, 2002
We develop the analytical method of field momenta for analyzing the dynamics of optical vector solitons in photorefractive nonlinear media. First, we derive the effective evolution equations for the parameters of multi-component solitons composed of ...
