Photorefractive polymers with high diffraction efficiency in the visible and near-infrared
regions of the electromagnetic spectrum have been developed. These polymers, which have …

Photorefractive materials can form" instant" holograms without time-consuming development
steps. Their potential applications include image processing, optical data storage, and …

PHOTOREFRACTIVE materials are of considerable interest for the development of all-
optical devices1. The photoref ractive effect appears in materials that exhibit an electric-field …

Photorefractive polymers exhibit large refractive index changes when exposed to low power
laser beams. When the optical excitation consists of two interfering coherent beams, the …

A photorefractive polymer composite sensitized at 1550 nm through direct two-photon
absorption has been developed. We show an external diffraction efficiency of 3% in four …

A picture is worth a thousand—no, hundreds of thousands—of bits of information. If that
picture can be optically stored and retrieved, with the data bits moving in and out in parallel …

We demonstrate the use of a near-infrared-sensitive photorefractive polymer with high
efficiency for imaging through scattering media, using an all-optical holographic time gate …

Among the various applications for reversible holographic storage media,, a particularly
interesting one is time-gated holographic imaging (TGHI),,. This technique could provide a …

Abstract Holographic three-dimensional (3D) displays, provide realistic images without the
need for special eyewear, making them valuable tools for applications that require …

Materials demonstrating a photorefractive effect are principal candidates for numerous
applications, including high‐density optical data storage, optical image processing, phase …
