A novel concept for implementing a high-resolution spatial light modulator using a thin slab
of photorefractive LiNbOs crystal is described. This method uses the photovoltaic effect to …

High performance spatial light modulators (SLMs) are essential in many optical information
processing and computing applications for converting incoherent images to coherent …

An introduction to photorefractive devices is provided, which compares the basic operation,
fundamental functional capabilities, and performances of these devices. Applications of …

We demonstrate a new type of optically addressed spatial light modulator. By imaging an
external grating into a photorefractive material, we write holographic gratings without the …

Any digital optical processing (DOP) system requires basic computational modules such as
logic, memory, and shifting. Logic modules which utilize photorefractive crystals have been …

We demonstrate a technique by which the temporal oscillations in the response of a
photorefractive square-law converter, a recently developed high-contrast spatial light …

8.1 Background Optically addressed SLMs are essentially reversible photosensitive media
that are used as input devices in real-time coherent optical processing systems. On these …

The physics of the photorefractive effect and the unique nonlinear optical properties of
photorefractive crystals are described. A survey of the optical applications of the …

Photoaddressed spatial light modulators (SLMs) or light valves generally employ a
longitudinal electro-optical effect, where the electro-optic voltage is controlled by a …
