A photorefractive filter with 0.02 nm bandwidth was constructed. Using the Kukhtarev's
charge transport model, the spectral response and electrical tuning of the photorefractive …

An angular selectivity through the focused readout beam is geometrically analyzed and
experimental results are presented. Based on the analysis of geometrical results, we derive …

The independent characteristic of the angular selectivity for the writing conditions was
presented in photorefractive grating. In general, the incident angle of writing beam and the …

The photorefractive (PR) materials offer the real-time, erasable, high capacity, and parallel
accessible capabilities, that warrant applications to variety of photonics devices. In this …
