It is theoretically shown that discrete nonlinear surface waves are possible in waveguide
lattices. These self-trapped states are located at the edge of the array and can exist only …

We demonstrate, experimentally and theoretically, surface-wave solitons occurring at the
interface between a dielectric medium (air) and a nonlinear material with a very long-range …

A laser beam propagating in a photorefractive crystal generates a refractive-index profile
that deflects the beam to one side. This nonlinear deflection can be balanced by total …

The photorefractive surface waves with photorefractive nonlinearity of diffusion, drift, and
photovoltaic effect is studied numerically for the first time. We find out that the essential …

Excitation of nonlinear surface waves is studied at the SBN-75 crystal—air interface. The
SBN-75 crystal is characterised by the diffusion-type photorefractive nonlinearity, the surface …

Based on the calculation of the electrostatic field potential of space charges, we have
analysed the characteristic features of light-induced scattering of extraordinary polarised …

We consider a steady-state nonlinear photorefractive surface wave (PR SW) with TE or TM
polarisation when the refractive index of the photorefractive crystal (PRC) depends on the …

Propagation of the light beam in a thin photorefractive crystal with the diffusion-type
mechanism of nonlinearity has been studied both experimentally and theoretically. Total …

Surface-wave solitons, induced by the pyroelectric effect, are formed at the interface
between a photorefractive ferroelectric medium and a linear medium. These optical solitons …

We report the first observation, to our knowledge, of amplified scattering (beam fanning) in a
photorefractive polymer. The manifestations of beam fanning and the implications for two …
