Abstract

The derivation of the analytical form for index-contrast growth during hologram formation in a photorefractive-polymer composite is presented. The transfer function for chromophore rotation in an amorphous medium is found initially, and this is then convolved with an exponentially growing space-charge field to determine the index-contrast transient. This analysis reveals that index-contrast growth is fully characterized by just two parameters: the rise time of the space-charge field and the rotational diffusion constant. Good agreement between theory and measurement is found for a range of materials and experimental conditions.
