An overview of the properties of electron small polarons and bipolarons is given, which can
occur in the congruently melting composition of LiNbO 3 (LN). Such polarons influence the …

We present an overview of our research effort on volume holographic digital data storage.
Innovations, developments, and new insights gained in the design and operation of working …

Optically gated recording and nonvolatile readout in a digital volume holographic data
storage system that uses a pair of mutually incoherent light sources during recording and …

We describe a two-center holographic recording method for the storage of persistent
holograms in doubly doped lithium niobate crystals. We use a two-center model, and we …

We explored a number of factors affecting the properties relevant to holographic optical data
storage by using a two-color recording scheme in reduced, near-stoichiometric lithium …

Through the first-principles local-density-approximation+ Hubbard-U (LDA+ U) electronic-
structure calculation method, the microscopic properties of the Nb antisite (Nb Li) and the …

We present a new model for the two-photon photorefractive recording process. We solved
the resulting set of nonlinear coupled partial differential equations of the model within a …

In recent years, there has been a rapid expansion in the field of nonlinear optics as weIl as
in the field of neural computing. Up to date, no one would doubt that nonlinear optics is one …

Steady-state bright (or dark) spatial solitons are predicted for biased two-photon photovoltaic-
photorefractive materials due to two-photon photorefractive effects. These solitons differ from …
