Abstract

The self-focusing of two-dimensional Gaussian beams in cubic photorefractive optically active crystals of the (1-bar 1-bar 0) cut in the external electric field arbitrarily oriented in the cut plane is theoretically studied. The ranges of orientation of the external electric field are found in which the divergence of the light beam is smaller than the diffraction divergence. The dependences illustrating the existence of two-dimensional spatial solitons in a 15-mm-thick Bi{sub 12}SiO{sub 20} crystal are constructed taking into account the optical activity or neglecting it. The shape of a light beam propagating in the crystal is determined. (nonlinear optical phenomena)

Effect of optical activity on the self-focusing of light beams in cubic photorefractive crystals

Journal Article Shepelevich, V V ; Matusevich, V ; Golub, A A ; ... - Quantum Electronics (Woodbury, N.Y.)

The self-focusing of Gaussian light beams and the propagation of screening spatial solitons in a cubic optically active photorefractive crystal with the (1-bar 1-bar 0) cut plane are studied for an arbitrary orientation of an external electric field in this plane. A change in the rotation of the polarisation plane caused by the nonlinear interaction of light with the crystal is studied theoretically. It is shown that optical activity enhances self-focusing in some cases. Screening self-focusing was observed in an incoherently illuminated Bi{sub 12}SiO{sub 20} crystal without additional laser irradiation. The experimental data well agree with the proposed theoretical model.more » (nonlinear optical phenomena)« less

Interaction of screening solitons in cubic optically active photorefractive crystals

Journal Article Shepelevich, V V ; Golub, A A ; Kowarschik, R ; ... - Quantum Electronics (Woodbury, N.Y.)

The coherent interaction of Gaussian light beams polarised parallel to the [1bar10] direction in a cubic optically active photorefractive crystal with the [1-barbar1 1-bar 0] cut is studied in an electric field applied to the crystal in the [0 0 1-bar] direction. The effect of optical activity on the interaction of the light beams with the phase difference {Delta}=0, {pi}/2, and {pi} is theoretically studied. It is shown that, while a change in the intensity of a combined light beam at {Delta}=0 caused by the influence of optical activity in a 9-mm thick Bi{sub 12}TiO{sub 20} crystal is comparatively smallmore »« less

Spatial solitons in two-photon photorefractive media

Journal Article Hou Chunfeng ; Pei Yanbo ; Zhou Zhongxiang ; ... - Physical Review. A

We provide a theory for spatial solitons due to the two-photon photorefractive effect based on the Castro-Camus model [Opt. Lett. 28, 1129 (2003)]. We present the evolution equation of one-dimensional spatial solitons in two-photon photorefractive media. In steady state and under appropriate external bias conditions, we obtain the dark and bright soliton solutions of the optical wave evolution equation, and also discuss the self-deflection of the bright solitons theoretically by taking into account the diffusion effect.

Vector two-wavelength interaction on reflection holographic gratings in cubic gyrotropic photorefractive crystals

Journal Article Plesovskikh, A M ; Shandarov, S M ; Mart'yanov, A G ; ... - Quantum Electronics (Woodbury, N.Y.)

The interaction of two counterpropagating light waves on reflection holographic gratings is studied in cubic photorefractive crystals with the natural optical activity. The anisotropy of contributions from intramode (without a change in the refractive index of natural circularly polarised waves) and intermode processes to the interaction of the waves in a bismuth titanate crystal is considered. It is shown that the polarisation dependences of the effective gain and the polarisation vectors of the interacting light beams measured at a wavelength of 633 nm in a (100) cut Bi{sub 12}TiO{sub 20}:Fe, Cu crystal of thickness 2.6 mm well agree with numericalmore »« less

Propagation of spatial optical solitons in a dielectric with adjustable nonlinearity

Journal Article Alberucci, A. ; Piccardi, A. ; Peccianti, M. ; ... - Physical Review. A

We investigate spatial optical solitons propagating in a medium with a saturable but adjustable nonlinearity and a fixed degree of nonlocality. We employ nematic liquid crystals in a planar cell with optical properties tuned by an external voltage and solitons excited in the near infrared. We also demonstrate soliton self-bending versus excitation due to nonlinear variations in walk-off. A theoretical model accounting for the longitudinal derivatives is employed to compute the refractive index distribution and is found in excellent agreement with the experimental data.
