“…The above analysis for different polarized light beams indicates that the position of LC PR SWs can be changed by the polarization of incident light beams, while the position of PR SWs in inorganic PR crystals is polarization independent [3][4][5][6]. Moreover, the penetration depth of LC PR SWs can be controlled by means of the applied electric field, while the penetration depth of PR SWs in inorganic PR crystals is electric field independent [6].…”

“…Surface waves (SWs) can form in a photorefractive (PR) material due to PR nonlinearity [1][2][3][4][5][6]. The most attractive feature of PR SWs is that the concentration of beam energy in the narrow layer near the surface ensures that various nonlinear surface optical phenomena can be enhanced [3][4][5]. Up to the present, almost all of the PR SWs have been generated in inorganic PR crystals, such as LiNbO 3 , BaTiO 3 , Sr 0.6 Ba 0.4 NbO 3 and so on.…”

We predict the formation of electrically and optically controlled photorefractive surface waves in liquid crystal, with orientational photorefractive effects. In contrast to the case for photorefractive surface waves in inorganic crystals, the penetration depth of photorefractive surface waves in liquid crystal can be controlled by means of the applied external electric field, while the position of the photorefractive surface waves in the liquid crystal can be controlled by means of the applied external electric field and the polarization of incident light beams.

Ferroelectric lithography, a recent method of fabricating functional interfaces, traditionally involves photoreduction on polarized ferroelectric surfaces at optical energies above the bandgap of the ferroelectric. In this work, for the first time, photochemical deposition of elemental Ag nanoparticles on a specifically poled lithium niobate substrate is reported, with a broad white‐light spectrum transmitted through the crystal. The transmitted light has energies only below the bandgap, leading to the conclusion that the Ag reduction proceeds through non‐linear effects, specifically, second harmonic generation.
