Rigorous coupled-wave diffraction analysis of stratified volume photopolymer holograms

Stratified volume holograms (SVHs) have been studied1,2 in the layered structures of holograms that are useful for several applications in optical communication such as an optical wavelength-selective filter. The hitherto investigation was performed by using the beam propagation method (BPM) to emulate the SVH with thin (Raman-Nath) gratings, taking into no account the reflection at the boundaries. Here we develop a rigorous coupled-wave model to analyze the TE-polarized diffraction properties of stratified volume photopolymer holograms. The numerical and experimental angular selectivities of stratified holograms are shown.
