We have studied holographic grating recording in Fe-doped photorefractive crystals LiNbO3 (LN) and in doped As-S-Se chalcogenide glassy semiconductor (CGS) films. Transmission gratings in α-cut crystals of LN are efficient enough to demonstrate effect of optical channeling. Volume gratings recorded in LN crystals may be used as a parallel array of the planar waveguides. For the CGS slanted grating geometry was tested, aiming on creation of asymmetric blazed gratings. Asymmetry of non-Bragg diffraction orders was observed and it was 12 times enhanced by a gold coating. For the first time reflection volume grating were recorded in 2mm thick CGS by green solid state laser (λ=532nm, P=100mW). |
