Abstract

Photorefractive materials have many potential photonic applications, including dynamic holographic storage and image processing. Recently, amorphous organic photo refractive materials have emerged as a new class of photorefractive materials, offering wide structural flexibility, easy processability, and low cost at very high performance levels. Progress in this field has led to absorption-limited complete diffraction for the readout of a hologram stored in materials of only 100-150 μm thickness and to extremely large net gain coefficients of more than 200 cm¹, compared with 40-50 era⁻¹ in the best inorganic photorefractive crystals known to date
