Rhythmic Soliton Interactions for Integrated Dual-Microcomb Spectroscopy

Physical Review X
Soliton waves are sustained by a self-created index potential well, and their interactions occur when the potential well is invaded by other solitons. The interactions are important to soliton compounds in plasma, Bose-Einstein condensation, and optical ...

Quasinormal Modes of Optical Solitons

Physical Review Letters
Quasinormal modes (QNMs) are essential for understanding the stability and resonances of open systems, with increasing prominence in black hole physics. We present here the first study of QNMs of optical potentials. We show that solitons can support QNMs, deriving a soliton perturbation equation and giving exact analytical expressions for the QNMs of ...

Quenched dynamics of two-dimensional solitons and vortices in the Gross-Pitaevskii equation

, 2012
We consider a two-dimensional (2D) counterpart of the experiment that led to the creation of quasi-1D bright solitons in Bose-Einstein condensates (BECs) [Nature 417, 150--153 (2002)].

Single- and double-vortex vector solitons in self-focusing nonlinear media

, 2004
We study two-component spatial optical solitons carrying an angular momentum and propagating in a self-focusing saturable nonlinear medium. When one of the components is small, such vector solitons can be viewed as a self-trapped vortex beam that guides ...

Soliton-effect optical pulse compression in CMOS-compatible ultra-silicon-rich nitride waveguides

APL Photonics, 2019
The formation of optical solitons arises from the simultaneous presence of dispersive and nonlinear properties within a propagation medium. Chip-scale devices that support optical solitons harness high field confinement and flexibility in dispersion ...

Conservation laws, stability analysis, and dynamics of dispersive optical soliton solutions for higher-order nonlinear Schrödinger model with applications in single-mode optical fibers

AIP Advances
The propagation of ultra-short light pulses in a monomode optical fiber is governed by a higher-order nonlinear Schrödinger equation, which constitutes its foundation.
