Photorefractive screening-photovoltaic solitons are observed in lithium niobate. Two-
dimensional bright circular solitons are formed thanks to a strong static bias field, externally …

In this Letter, the first implementation, to our knowledge, of X-junctions between
photorefractive soliton waveguides in lithium niobate-on-insulator (LNOI) films is reported …

We present the evolution equation of one-dimensional spatial soliton in two-photon
photorefractive media under open-circuit conditions. In the steady state regime, our solutions …

We report the first experimental observation of spatial solitons with complex polarization
states, called the Poincaré polarization solitons (PPSs) in lead glass with strongly nonlocal …

We numerically and experimentally demonstrate the nonlinear continuous modulation of
orbital angular momentum (OAM) of a linearly polarized high-order Bessel beam in a biased …

We characterize the process of soliton waveguides (SWGs) recording at 405 nm wavelength
using pyroelectric effect in lithium niobate (LN) crystals. We experimentally study and …

Abstract We analyse the (2+ 1) D soliton formation in photorefractive crystals with strong
optical activity. The complete characterization of a soliton in such a crystal requires a careful …

The spectral dependences of absorption photoinduced in a pure bismuth titanium oxide
crystal by 532-nm laser pulses are studied. It is shown that optical absorption in the crystal in …

In the present paper we review the physics of soliton formation in lithium niobate by means
of photorefractive nonlinearity. Considering the waveguides that such solitonic beams leave …
