Journal ArticleDOI
How does an inclined holding beam affect discrete modulational instability and solitons in nonlinear cavities
TL;DR: Light propagation in arrays of weakly coupled nonlinear cavities driven by an inclined holding beam is studied and a crossover between resting and moving cavity solitons is analyzed, and novel features in the soliton collision are observed.
Journal ArticleDOI
Nonlinear phase shift and all-optical switching in quasi-phase-matched quadratic media
TL;DR: This work analytically studies the influence of this induced cubic nonlinearity on the amplitude and phase modulation of the fundamental wave and predicts efficient all-optical switching.
Journal ArticleDOI
Soliton interactions and transformations in colloidal media
TL;DR: In this paper, the existence and properties of one-dimensional self-trapped beams spatial optical solitons in such media and demonstrate the existence of a bistability regime were analyzed.
Journal ArticleDOI
Wave scattering on a domain wall in a chain of PT-symmetric couplers
TL;DR: In this article, the authors studied wave propagation in linear arrays composed of pairs of conjugate waveguides with balanced gain and loss, where the linear spectrum is known to feature high-frequency and low-frequency branches.
Journal ArticleDOI

TL;DR: The implementation of this parametric process for characterisation of femtosecond pulses is demonstrated, enabling the estimation of pulse width, chirp, and front tilt through monitoring the evolution of the autocorrelation trace inside the nonlinear crystal.
