We propose complex networks constructed from interacting vector solitons. Within soliton-based networks, we demonstrate memory effects that are greatly enhanced by noise, as well as spontaneous entire network self-synchronization effects.
Laser dynamics of asynchronously modelocked Er-fiber soliton lasers is investigated theoretically and experimentally. The pulse parameters are found to exhibit complicated slow periodic variations and can be examined experimentally by analyzing the RF spectra.
An interface between two periodic 1D arrays with self-focusing Kerr nonlinearities is shown experimentally to support strikingly different families of surface solitons due to differences in surface potential near the boundary.
We study, theoretically and experimentally, nonlinear dynamics of a wavepacket launched inside a potential well. Increasing the power of the wavepacket transforms its dynamics from linear tunneling, to soliton tunneling, and eventually to soliton emission.
We show that gap solitons self-average fluctuations in random gratings. The soliton trapping inside the grating is explained. The correlation functions of the force and the potential acting on the gap soliton are found.
Quasi super continuum generation for ultrahigh resolution optical coherence tomography is demonstrated using ultrahigh speed wavelength tuning of femtosecond soliton pulse. In this light source, center wavelength, bandwidth, and spectrum shape can be changed arbitrarily.
We investigate asymptotic pulse shapes arising from a balance of Kerr-type and plasma-mediated self-amplitude modulations. These self-stabilizing soliton-like solutions closely resemble experimental data and constitute the major mechanism for self-compression in femtosecond filaments.
We propose a simple two-stage model of supercontinuum formation for nanosecond-long pulse. First the sea of solitons is formed, then the spectrum is broadened by Raman interaction. We found a good correspondence with experiments.
We derive an analytic formula for the lateral dynamics of solitons in a general inhomogeneous nonlinear media and demonstrate numerically that it can be valid for tens of diffraction lengths.
A widely tunable femtosecond light source based on a Cr:Forsterite laser and a nonlinear photonic-crystal-fiber is reported. With a 910 nm tuning range, this simple, easily-tunable, and low-cost source could be widely applicable for many applications.
We show that a nonconventionally biased photorefractive crystal can support one-dimensional spatial solitons. Transition from bright to dark, and from discrete to gap solitons is realized for the first time by varying optical beam orientation.
We report a novel mechanism of localization and frequency up-conversion of light pulses with spectra in the normal GVD range of optical fibres, due to the inertial force acting on pulses from the accelerating solitons.
We numerically analyze supercontinuum generation in a long length of tapered PCF to understand the soliton trapping dynamics leading to the enhanced Blue/UV supercontinuum recently achieved experimentally in such fibers.
We investigate the effect of nonlinearity in novel parity-time (PT) symmetric potentials. We show that new types of nonlinear self-trapped modes can exist in optical PT synthetic lattices.
A new modelocking regime governed by the Ginzburg-Landau equation is demonstrated in an anomalous dispersion fiber laser. Output pulses are long, flat-topped, and highly-down-chirped, with energies above 150 nJ and repetition rates below 300 kHz.
Fiber lasers modelocked by filtering of a chirped pulse are analyzed with the Ginzburg-Landau equation. A range of experimental pulse shapes are predicted remarkably well by an exact analytical solution, and constitute dissipative temporal solitons.
We report numerical investigation of the soliton self-frequency shift in air-core photonic crystal fibres, accompanied by the emission of Airy waves and strong cut-off of the input pulse spectrum due to Raman response of air.
We observe modulational instability and pulse train generation in an integrated waveguide Bragg grating written in highly nonlinear chalcogenide glass. This Bragg soliton effect occurs at pulse energies 10,000 times lower than any previous reports.
We investigate a novel approach for ultrahigh-power soliton-induced supercontinuum generation based on argon-filled metal-dielectric hollow waveguides and predict the generation of MW/nm spectral power densities with ~0.1 mJ energy and self-compressed isolated 1.7-fs pulses.
