The observation of a novel noncollinear optical second-harmonic generation mechanism is
reported. In strontium barium niobate crystals, a circular cone of second-harmonic light is …

Photoinduced light scattering (PILS) in nominally undoped LiNbO 3 with the mixed
photovoltaic and diffusion charge transports is studied theoretically and experimentally. All …

High-intensity single-beam photorefractive data on LiNbO3 show the occurrence of a well-
defined intensity threshold for enhanced deterioration (fanning) of the output beam. That …

A driven-dissipative nonlinear photonic system (eg, exciton-polaritons) can operate in a
gapped superfluid regime. We demonstrate theoretically that the reflection of a linear wave …

We study theoretically the dependence of the photorefractive response ofa periodically
poled ferroelectric on the spatial frequency of light fringes, on the period of the domain …

In this chapter, the standard model accounting for the photorefractive nonlinearity in a
material is presented. The mathematical formalism of the rate equations has been …

Two-dimensional electron gases (2DEGs) were demonstrated in indium–tin–oxide (ITO)-
coated lithium niobate (LN) slabs by monitoring the very first reflection (VFR). Being dictated …

Two dimensional electron gases (2DEGs) formed at interfaces between two oxides have
been drawing growing attention for their intriguing magnetic, superconducting, and optical …

Great impact of surface plasmon polaritons (SPPs) on photorefractive effect in ZnSe/liquid
crystal interface was observed and studied in dye pyrromethane 597 doped 4, 4'-n …

A phenomenological approach, in which the current density is related in some functional
manner to the electric field and to the light intensity, is developed. The validity and …
