| Abstract: | Abstract Numerical studies of non-sinusoidal holographic gratings are reported. It is assumed that losses are present during the hologram recording process. At reconstruction the structures are treated as pure-phase volume gratings. The photo induced changes in the refractive index of the material are described by an exponential saturation law. Angular and wavelength selectivities of unslanted transmission and reflection gratings are evaluated. |
