“…Besides, observations with the micro-interferometer (Zygo Corporation) have not revealed notable light-induced relief in the irradiated area with the an accuracy of 10 nm. This means that possible polarization gratings caused by light-induced anisotropy in the film [11][12][13][14], as well as the phase gratings caused by light-induced micro-relief [14,29,30], were negligibly weak, if recorded at all.…”

“…To our best knowledge, Kwak et al [11] first proposed and used a chalcogenide film as a material for recording polarization holograms. Later, Mitkova et al [12,13], Ozols et al [14] and Asatryan et al [15] reported on the characteristics of the polarization recording in different types of chalcogenides. Despite many attractive features of the chalcogenide materials (exclusive chemical and thermal stabilities, possibility to control an absorption range and anisotropy characteristics by the composition variation, onestep recording, etc.…”

Polarization gratings have been recorded in a combined liquid crystal (LC) cell made of a substrate covered with a photosensitive chalcogenide orientation layer and a reference substrate covered with a rubbed polyimide film. The gratings are formed due to the spatially modulated light-induced easy orientation axis on the chalcogenide surface recorded by two beams with opposite circular polarizations. The gratings are permanent, but they can be erased by one of the recording beams and re-recorded. The diffraction intensity of the circularly polarized light is achromatic and does not depend on the birefringence of the LC. The diffraction efficiency of the grating is of the order of a few percents. Application of an ac field causes a strong increase of the diffraction efficiency up to 45%.

“…Such a holographic element allows an easy and real-time measurement of the Stokes parameter S 3 . The possibility of a polarization grating inscription in amorphous chalcogenide Se 70 Ag 15 I 15 film with right and left circularly polarized (hereafter called RCP and LCP, respectively) Ar + laser beams has been demonstrated by Mitkova et al in [4].…”

“…Chalcogenide glasses have drawn colossal attention over the past three decades because of their potential in photoresist [1,2], microelectronic [3][4][5], optoelectronic [6][7][8][9], holographic [10,11] applications and especially their ability to transmit light in the midto far-infrared region. Impurity effects in chalcogenide glasses may have importance in fabricating glassy semiconductors.…”
