    Optimization strategy to find shapes of soliton molecules

    Frequently, a certain solution of a nonlinear wave equation is of interest, but no analytic form is known, and one must work with approximations. We introduce a search strategy to find solutions of the propaga...

    Rogue wave formation by accelerated solitons at an optical event horizon

    Rogue waves, by definition, are rare events of extreme amplitude. At the same time, they are surprisingly ubiquitous, in the sense that they can exist in a wide range of physical contexts and possess probabili...

    A fiber Mach–Zehnder interferometer for the unique phase retrieval of ultrafast pulses with a 1 THz gap

    Unique phase retrieval of ultrashort pulses with well-separated frequency components was demonstrated using a cross-correlation technique with a conditioning filter. Here, this filter was designed as an unbala...

    A useful approximation for the cladding index of holey fibers

    We present a simplified quantitative description of the effective refractive index of the cladding region in holey fibers. Our approximation is based on a smooth interpolation between two limiting cases. It re...

    Soliton content of arbitrarily shaped light pulses in fibers analysed using a soliton-radiation beat pattern

    Arbitrarily shaped light pulses propagating down a fiber may contain one or several solitons and a radiative background. A novel computer-assisted method is introduced to identify the composition. This techniq...

    Soliton propagation in a dispersion map with deviation from periodicity

    Solitons in dispersion-managed fibers are a particular case of a periodically perturbed nonlinear system. Since in practice random deviations from strict periodicity of the dispersion alternation are unavoidab...

    Experimental investigation of Risken–Nummedal–Graham–Haken laser instability in fiber ring lasers

    It has been suggested (by Pessina et al. in 1997) that the observed spontaneous mode beating of erbium-doped-fiber ring lasers can be explained as the multimode instability described in 1968 by Risken and Numm...

    Role of field losses on the Risken–Nummedal–Graham–Haken laser instability: application to erbium-doped fibre lasers

    We analyse the effect of both distributed and localised losses in a laser cavity on the Risken–Nummedal–Graham–Haken multimode instability. For two-level lasers, distributed losses are found to have a negligib...

    Manipulation of soliton ensembles by spectral filters

    It was shown recently that an ensemble of solitons can be created in a driven optical fiber resonator. The ensemble can exist in either an ordered or a disordered state; these have been referred to as soliton ...

    Superluminal pulse propagation in an erbium fiber laser

    It is well known that saturating gain media can give rise to superluminal pulse propagation velocity. In most mode-locked lasers the effect is unmeasurably small and has not yet been directly demonstrated. We ...

    Self-stabilizing additive-pulse mode-locking due to thermo-optical non-linearity in an optical fiber

    , 1671 (1991)] described a Nd:YLF APM laser which somehow automatically adjusted the relative resonator phase. We reproduce this behavior and analyse its origin. Thermal effects due to the light power guided i...

    On the pulse width of synchronously pumped lasers

    The pulse width of a synchronously pumped laser chiefly depends on the available cavity bandwidth and the pump-pulse duration. A functional form of this dependence was suggested in the literature. We present a...

    Longitudinal structure formation in a nonlinear resonator

    A fiber ring resonator, synchronously driven by picosecond pulses, exhibits a spatiotemporal instability. A rapid modulation in the pulse envelope is spontaneously formed and evolves dynamically. This structur...

    Velocity of pulse propagation in media with amplitude nonlinearity

    The propagation velocity of optical wave fronts can be accelerated by the influence of gain saturation. We report systematic measurements for the specific case of Brillouin gain in optical fibers. A simplified...

    Complexity out of a simple structure: The intricate multistable behaviour of an optical resonator filled with sodium atoms

    A Fabry-Perot resonator containing sodium atoms displays a variety of switching phenomena even in the simplified case of homogeneous broadening. The processes are shown to arise from the combined effects of Ze...
