Polarization holographic recording of diffractive elements on amorphous chalcogenide nanomultilayers

Abstract

In contrast to the conventional holographic process, in which intensity variations in an interference pattern between an object beam and a reference beam are recorded, polarization holography employs beams with two different polarizations for recording information. In this case, the polarization state of the resultant beam is recorded on a suitable medium. In present work we have shown that nanomultilayers structures (NML) based on ChG-Se are sensitive to different states of polarizations of recording beams which gives the possibility to increase the diffraction efficiency of patterned surface relief gratings.
