This paper discusses optically controlled structures with a modulating liquid-crystal layer and an Sb2S3 photoconductor with a sublayer made from germanium glass of composition As_17.6S_26.4Ge_17.5Se_38.5 (IKS24). It is shown that the response rate of the indicated structure is greater by a factor of 4 than that of the Sb2S3-liquid-crystal control structure with no sublayer. With reversible writing of thin holograms, a recording regime with a nonsymmetrical line profile is implemented that makes it possible to obtain a diffraction efficiency of 41.5% on the structures with a sublayer. |
