Abstract
On the basis of vectorial coupled-wave theory, the diffraction of optical waves by finite bounded volume holographic grating is described, taking into account polarizations of the reference beam and the subject beam, variation of the average dielectric constant and the modulation depth. The deduced set of coupled-wave equations restricted in a bounded volume is solved numerically by means of the Runge-Kutta calculation. The intensity distributions of the transmitted and diffracted beams are strongly influenced by the modulation depth, the polarization of incidence and the variation of average dielectric constant. It is demonstrated that a high coupling coefficient volume holographic grating may considerably distort the shape of the output beams. We can optimize intensity distributions of the output beams and provide the way for further improvement.
