Abstract
Photochromic dyes like the fulgides `Aberchrome 540' and `Aberchrome 670' have been investigated in the polymer films with respect to the formation of holographic gratings. For high exposure doses the diffraction efficiencies tend to decrease with additional exposure. This is discussed in terms of nonlinear gratings due to the photochromic mechanism in a 2 level model. Two methods for the fabrication of latent photochromic gratings, which can be switched on by a homogeneous noncoherent exposure are discussed.
