This review describes the current state‐of‐the‐art of photorefractive polymers for
holography. The analysis of this rich field begins with a brief historical perspective followed …

Light-induced changes in optical properties such as refractive index and absorption
coefficients are always related to material excitation, ie deviation from (thermal) equilibrium …

We study detuning effects that modify the Bragg condition in photorefractive crystals and
analyze the influence of these effects on the retrieval of information that is stored in such …
