Photorefractive multiple quantum well materials and applications to signal processing

A promising new class of photorefractive devices using multiple quantum well materials provide the largest index changes ( Δn ∼ 0.06) and the lowest writing energy densities (1 μJ/cm 2) of any photorefractive material. I will review our work on devices operating in the 600 nm and 850 nm wavelengths...

Description
Summary:A promising new class of photorefractive devices using multiple quantum well materials provide the largest index changes ( Δn ∼ 0.06) and the lowest writing energy densities (1 μJ/cm 2) of any photorefractive material. I will review our work on devices operating in the 600 nm and 850 nm wavelengths and discuss some demonstrations of applications of these materials in information processing.
