Recently, the optical recordings using polar liquid crystals - synclinic SmC* and anticlinic SmC*A phases at the surface stabilized ferroelectric liquid crystal structures (SSFLC) were reported (Sutkowski et al., 2009) [2]. Among the others, SSFLCs provide such attractive properties like submicrosecond switching and the easily induced memory effect, which are desired at contemporary re-writable holography applications. Using SS(A)FLC the micrometer size gratings are also generated (Clark and Lagerwal, 1980) [3]. Here we present a study of the performance of recording of a phase grating of 20 micron resolution using custom fabricated measuring cells with photosensitive orienting layers. The photo- and electro-optical properties of the selected synclinic SmC* and anticlinic SmC*A structures have been examined and presented. Various operating modes of studied structures are shown and described. The charge transfer mechanism of the optically driven switching is proposed and discussed.
