Frequency and phase locking of laser cavity solitons [PDF]

open access: yes, 2012
Self-localized states or dissipative solitons have the freedom of translation in systems with a homogeneous background. When compared to cavity solitons in coherently driven nonlinear optical systems, laser cavity solitons have the additional freedom of ...

Mulitiscale spatiotemporal structures in mode-locked fiber lasers [PDF]

open access: yesLaser Physics Letters, 2020
Abstract Using an Er-doped fiber laser as a test bed, here we for the first time experimentally demonstrate the simultaneous effect of the fast scale (round-trip time) and slow scale (thousands round-trip time) instabilities on the emergence of breathers similar to the Akhmediev breathers, Peregrine solitons, and partially mode-locked

Study of millimeter wave phase shift in 40 GHz hybrid mode locked lasers [PDF]

open access: yes, 2009
An investigation into using hybrid mode-locked lasers to implement millimeter wave phase shift is presented. The phase shift is measured directly using a vector network analyzer enabling straightforward characterization of such systems.

Mode locking and spatiotemporal chaos in periodically driven Gunn diodes [PDF]

open access: yesPhysical Review B, 1990
Numerical simulation is applied to study the highly nonlinear-dynamic phenomena that can arise in Gunn diodes by interaction between the internally generated domain mode and an external microwave signal. By adjusting the time of domain formation and the speed of propagation, the internal oscillation entrains with the external signal.

A hybrid mode locked laser as millimetre wave modulated data source for radio-over-fiber systems [PDF]

open access: yes, 2009
The paper presents a characterisation of a hybrid mode locked laser under external injection locking. It shows how such a system can be used to transmit baseband data without the requirement of an external ...

Spatiotemporal Wavevector Dynamics in Transverse Mode-Locked Beams

open access: yes2025 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC)
The phase-locking of transverse higher-order resonator modes results in a beam with rapidly oscillating spatial intensity profile. To complete the description of such transverse mode-locked (TML) beams, their spatiotemporal phase dynamics are explored in this work.
