Abstract

Abstract Efficiencies of thick photochromic absorption gratings are theoretically investigated. The treatment is based on a realistic photochromic grating model, which includes both spatial and temporal variations of the absorption coefficient. Simple analytic solutions for dynamic diffraction characteristics are derived. This nonlinear model shows that the maximum diffraction efficiency of photochromic absorption gratings may exceed 10%.
