Two-dimensional localized states in an active phase-field-crystal model
Lukas Ophaus, Edgar Knobloch, Svetlana V. Gurevich +1
The active phase-field-crystal (active PFC) model provides a simple microscopic mean field description of crystallization in active systems. It combines the PFC model (or conserved…
Influence of optical feedback on harmonic pulsating solutions of long-cavity mode-locked VECSELs
A. Bartolo, T. Seidel, N. Vigne +8
We analyse the effect of optical feedback on the dynamics of external-cavity mode-locked semiconductor lasers operated in the long cavity regime. Depending on the ratio between the…
Localized states in passive and active phase-field-crystal models
Max Philipp Holl, Andrew J. Archer, Svetlana V. Gurevich +3
The passive conserved Swift-Hohenberg equation (or phase-field-crystal [PFC] model) corresponds to a gradient dynamics for a single order parameter field related to density. It pro…
How carrier memory enters the Haus master equation of mode-locking
Jan Hausen, Kathy Lüdge, Svetlana V. Gurevich +1
We present a generalization of the Haus master equation in which a dynamical boundary condition allows to describe complex pulse trains such as the Q-switched and harmonic transiti…
Phase-field crystal description of active crystallites: elastic and inelastic collisions
Lukas Ophaus, Johannes Kirchner, Svetlana V. Gurevich +1
The active Phase-Field-Crystal (aPFC) model combines elements of the Toner-Tu theory for self-propelled particles and the classical Phase-Field-Crystal (PFC) model that describes t…
Phase incoherent photonic molecules in V-shaped mode-locked VECSELs
Jan Hausen, Stefan Meineck, Julien Javaloyes +2
Passively mode-locked vertical external-cavity surface-emitting semiconductor lasers (VECSELs) composed of a gain chip and a semiconductor saturable absorber have been drawing much…
Bifurcations of front motion in passive and active Allen-Cahn-type equations
Fenna Stegemerten, Svetlana Gurevich, Uwe Thiele
The well-known cubic Allen-Cahn (AC) equation is a simple gradient dynamics (or variational) model for a nonconserved order parameter field. After revising main literature results…
Bound States of Light Bullets in Passively-Mode-Locked Semiconductor Lasers
Fabian Dohmen, Julien Javaloyes, Svetlana V. Gurevich
In this paper, we analyze the dynamics and formation mechanisms of bound states (BSs) of light bullets in the output of a laser coupled to a distant saturable absorber. First we ap…
Discrete Light Bullets in Passively Mode-Locked Semiconductor Lasers
Thomas G. Seidel, Auro M. Perego, Julien Javaloyes +1
In this paper, we analyze the formation and dynamical properties of discrete light bullets (dLBs) in an array of passively mode-locked lasers coupled via evanescent fields in a rin…
Topological Localized states in the time delayed Adler model: Bifurcation analysis and interaction law
Leon Munsberg, Julien Javaloyes, Svetlana V. Gurevich
The time-delayed Adler equation is arguably the simplest model for an injected semiconductor laser with coherent injection and optical feedback. It is able to reproduce the existen…
Dispersive instabilities in Passively Mode-Locked Integrated External-Cavity Surface-Emitting Lasers
Christian Schelte, Denis Hessel, Julien Javaloyes +1
We analyze the dynamics of passively mode-locked integrated external-cavity surface-emitting Lasers (MIXSELs) using a first-principle dynamical model based upon delay algebraic equ…
Two-dimensional patterns in dip coating -- first steps on the continuation path
Phong-Minh Timmy Ly, Kevin David Joachim Mitas, Uwe Thiele +1
We present a brief comparative investigation of the bifurcation structure related to the formation of two-dimensional deposition patterns as described by continuum models of Cahn-H…
