A narrow-bandwidth interference filter has been developed using volume holography in
photorefractive LiNbO 3 crystals. The device works as a Bragg reflector using a volume …

The steady-state field gratings recorded in photovoltaic photorefractive materials have been
investigated theoretically for high modulation's depths of the light intensity pattern (up to …

Lithium niobate (LiNbO3) is a paradigmatic photorefractive (PR) material. It provided the first
experimental evidence of the PR effect and still maintains a key position in the field. This …

Photovoltaic dependence of photorefractive grating (ie, space-charge field and phase-shift
of the index grating) on the externally applied dc electric field in photovoltaic–photorefractive …

Phase-conjugate (PC) reflectivity is one of the most important parameters that characterize
the four-wave mixing process in photorefractive (PR) materials. In this paper, the effect of the …

The obvious influence of the internal photoinduced electric field on the formation of self-
pumped phase conjugation in doped (K_0. 5Na_0. 5) _0. 2 (Sr_0. 75Ba_0. 25) _0 …

The intensity of oscillation and the oscillation frequency shift are two most important
parameters that characterize the performance of a photorefractive ring oscillator. In this …

A family of narrow linewidth integrated optical distributed Bragg reflector-(DBR-), distributed
feedback-(DFB-), and DBR-/DFB-coupled cavity lasers with Er-doped LiNbO 3 single-mode …

A simple analytical expression for the evolution of photorefractive grating was derived for
photovoltaic materials. The theory is based on the band transport model under the quasi-cw …

Mg: Fe: LiNbO 3, Ce: Fe: LiNbO 3 and Fe: LiNbO 3 crystals were grown by the Czochralski
method. The absorption spectra of these crystals were measured. It is shown in the results …
