Abstract
We analyze the propagation of pulses in noncentrosymmetric crystals by applying high-frequency expansions techniques for Maxwell equations. As a rst application we give a closed-form expression for the anisotropic di raction operator. Given this expression we identify a critical con guration in biaxial crystals where the di raction reduces to a one-dimensional second-order operator for the ordinary wave instead of the standard transverse Laplacian. The beam propagation in such a con guration involves the generation of spatial solitons because of this anomalous onedimensional di raction. As a second application we present closed-form formulas for the interference patterns from biaxial crystal plates between two polarizers. These formulas agree with experimental patterns.
