Summary: The study explores the impact of optical feedback on the dynamics of an external-cavity passively mode-locked surface-emitting laser, demonstrating that feedback acts as a solution selector that can either enhance or hinder the appearance of multistable harmonic arrangements of pulses. The theoretical analysis successfully replicates the experimental results and highlights asymmetrical resonance tongues caused by parity symmetry-breaking induced by gain depletion.

Summary: A novel and robust phenomenon has been uncovered where spatiotemporal Kerr cavity patterns in cylindrical microresonators gradually self-replicate. These patterns, which are inherently synchronized multi-frequency combs, experience transitions among patterns with different numbers of rows under proper conditions. The self-replications result in stepwise additions or removals of individual combs along the cylinder's axis in a fully reversible and deterministic way.

Summary: The emergence of wiggling temporal localized states in a passively mode-locked vertical external-cavity surface-emitting laser is analyzed. The wiggling instability stems from the interplay between third-order dispersion and frequency mismatch induced by micro-cavities. The homoclinic scenario underlying the wiggling phenomenon allows for control of oscillation parameters.

Summary: This study demonstrates that large-aspect-ratio VECSELs can operate in the spatiotemporal mode-locking regime. The emitted pulses have specific spatial profiles and temporal localization, which are important for studying spatiotemporal dynamics and multidimensional control of light.

Summary: The study focuses on the stability and attractor dynamics of an elongated Bose-Einstein condensate with dark or gray kink solitons in the presence of localized dissipation. It was found that there is a threshold value for the stabilization of the dark soliton, and above this threshold, attractor dynamics towards the dark soliton are observed. Additionally, the dark soliton was identified as the unique steady-state of the system for all initial conditions.

Summary: Theoretical investigation into quadratic dark localized dissipative states in cavity-enhanced second-harmonic generation reveals their dynamics, bifurcation structure, and stability. These states, formed through the locking of plane front waves, exhibit collapsed homoclinic snaking and potentially oscillatory dynamics.

Summary: In this study, oscillating and chaotic regimes of honeycomb patterns and dark cavity solitons were examined in a cavity displaying electromagnetically induced transparency. The numerical investigation of the transition to chaotically oscillating honeycombs in a three-level atomic system revealed the dynamical behavior for different control parameter values. It was found that oscillating dark cavity solitons coexist with the honeycomb patterns. The coherent oscillation of these solitons was achieved by selecting an appropriate separation distance, leading to the discovery of a novel regime of chimera states.

Summary: The properties of a running intrinsic localized mode (ILM) in electric, cyclic, dissipative, nonlinear 1D transmission lines are studied to quantify the parameter-dependent amplitude of the backwave. Balanced and unbalanced damping and driving conditions are considered. The design of a cyclic, dissipative self-dual nonlinear transmission line is achieved by introducing a unit cell duplex driver. When the self-dual conditions are satisfied, the fundamental backwave is no longer observed.

Summary: This experimental study investigates the nonlinear loss mechanism between traveling localized excitation and the underlying extended normal mode spectrum for a 1D lattice using three types of cyclic, electric, nonlinear transmission lines. It is found that supertransmission can be achieved when the two nonlinear terms are balanced in the capacitive+inductive NLTL configuration.

Summary: Modulation instability is a focusing mechanism that can generate strong wave localizations on water surfaces and in other nonlinear dispersive media. By studying the exact solutions of the nonlinear Schrodinger equation, it has been found that phase-shift localization applied to the background can trigger extreme events.

Summary: The collision of two self-trapped atomic matter wave packets in an optical ring cavity leads to various collision phenomena depending on the magnitude of colliding velocity. Different features are observed compared to the cavity-free case, with low velocity collisions resulting in oscillations, medium velocity collisions being highly phase sensitive, and high velocity collisions leading to packet fragmentation. Beyond a certain limit, the colliding wave packets exhibit behavior similar to classical particles before experiencing severe spatial spreading.

Summary: Confining photons in cavities enhances the interaction between light and matter. We have demonstrated how sidewall roughness in air-slot photonic-crystal waveguides can induce Anderson-localized modes with high quality factors and mode volumes below the diffraction limit. The interaction between these disorder-induced optical modes and in-plane mechanical modes is governed by a distribution of coupling rates, leading to mechanical amplification via optomechanical backaction. This study opens up new possibilities for exploring complex systems with mutually coupled degrees of freedom.

Summary: The study investigated the polarization dynamics in a free birefringence mode-locked fiber laser through numerical and experimental methods, revealing changes in ellipticity due to nonlinear birefringence in a 20-m long bi-twisted fiber. The inclusion of bi-twisted fiber allowed for independent investigation of nonlinear effects and linear effects.

Summary: This paper derives and analyzes the interaction equations governing the slow time evolution of two interacting temporal cavity solitons in a delay differential equation model of a nonlinear mirror mode-locked laser. The study shows that long-range soliton interaction can result in either harmonic mode-locking regime or closely packed incoherent soliton bound state, while short-range soliton interaction can lead to antiphase or in-phase stationary and breathing harmonic mode-locking regimes.

Summary: The delay differential equation model of a nonlinear optical-nonlinear amplifying loop mirror mode-locked laser takes into account the finite relaxation rate of the gain medium and asymmetric beam splitting at the entrance of the nonlinear mirror loop. The model demonstrates large windows of regular fundamental and harmonic mode-locked regimes with single and multiple pulses per cavity round trip time, separated by domains of irregular pulsing.

Summary: By utilizing an asymptotic technique, a generalized version of the class-B Haus partial differential equation mode-locking model has been developed, taking into consideration both the slow gain response and fast gain dynamics. The model not only describes the Q-switched instability of the fundamental mode-locked regime but also the leading edge instability leading to harmonic mode-locked regimes with increasing pump power.

Summary: This study investigates the interaction of dissipative solitons in an optical resonator with a photonic crystal fiber, using a generalized Lugiato-Lefever equation with fourth-order dispersion. The results show that positive fourth-order dispersion leads to increased interaction force between solitons and stabilizes multiple equidistant soliton bound states in the phase space. Additionally, spectral filtering, even at a small level, can reduce Cherenkov radiation at the soliton tails, weaken the interaction strength, and impact the stability of bound states.
