A simple method to trap and manipulate metallic micro/nano-particles on the surface of
photorefractive crystals is proposed. After inducing inhomogeneous charge density and …

Propagation characteristics and stability properties of two-component composite screening
photovoltaic spatial solitons have been analyzed in this paper. Employing paraxial ray …

The photorefractive (PR) effect plays a critical role in emerging photonic technologies,
including dynamic volume holography and on-chip all-optical functionalities. Nevertheless …

The non-diffracting Bessel beam approach was used for the first time for the elaboration of
photovoltaic tweezers. We report the trapping of dielectric microparticles of chalk (CaCO 3) …

The nonuniform 2D photovoltaic fields generated near the surface of a photorefractive Fe-
doped lithium niobate (LN: Fe) crystal by a nondiffracting optical Bessel beam with …

We experimentally demonstrated that dielectrophoretic (DEP) forces of alternating
photovoltaic fields generated near the surface of a photorefractive Fe-doped lithium niobate …

In the paper results of the investigation of the influence of electric properties of the
environment surrounding LiNbO3 crystals on photorefractive effect induced in these crystals …

In this paper, the nonlinearities resulting from the simple band transport model of
photorefractivity are compared with dependences experimentally obtained in LiNbO3: Fe …

In this paper we have studied the Linearity and Non-linearity of Photorefractive effect in
materials using the band transport model. For low light beam intensities the change in the …

This disertation is written in partial fulfillment of the requirements for the degree of Doctor of
Phylosophy, Ph. D., from the Technical University of Denmark. The work has been supported …
