We analyse modulation instability in fibre with longitudinally varying dispersion and the associated parametric amplification and confirm that modulation instability in such fibre is observed even in the case of positive dispersion. Highly nonlinear

The ‘Cabaret’ finite differences method allows the performance of fast and conclusive modelling of the microcavity temporal dynamics with group velocity dispersion, cross- and self- phase modulation included. The proposed scheme and model allow u

The state of a soliton is characterized by the eigenvalues of the Zakharov–Shabat problem. The data transfer rate in the fiber-optic communication lines that use eigenvalues for coding signals can be significantly increased only by developing optic

The spectral parameters of solitons result from the nonlinear Fourier transform for a pulse propagating in a fiber. A new approach for controlling the discrete component of spectral parameters is proposed. In the presence of a resonance between field

The spectral characteristics of an optically pumped external-cavity semiconductor disk laser near λ = 1320 nm are studied experimentally. Intracavity second harmonic generation is obtained using an LBO nonlinear crystal. The output power at a wavele

Use of dispersion oscillation fiber for all-optical coding in nonlinear Fourier transmission links is proposed. The dispersion oscillating fiber allows to prepare predefined set of discrete eigenvalues. Real part and imaginary part of the eigenvalues

Manipulation of initial chirp of input pulses in dispersion oscillating fibers provides precise control of the soliton fission process. Simulations demonstrate that pre-chirp can be applied to control amplitudes and carrier frequencies of output puls

Artificial periodic structures offers an additional degree of freedom in manipulation of nonlinear waves and solitons. It is shown that periodical variation of the coefficients of nonlinear Schrodinger equation allows to change soliton eigenvalues. P

A self-consistent numerical model for the self-sustained high-current pulsed discharge is constructed based on the solution of the equations of the population of H2 electronic and vibrational states. The model accounts for electronic, ion-molecular,

Generation of high-intensity pulses through inelastic soliton collisions in dispersion oscillating fibre is discussed. The inelastic collisions leads to the change amplitudes of solitons, group velocities and even of number of solitons. The generatio
