In this work we present the first realization and characterization of two-dimensional periodic and aperiodic POLICRYPS (Polymer Liquid Crystal Polymer Slices) structures, obtained by means of a single-beam holographic technique exploiting a high resolution spatial light modulator (SLM). A first investigation shows that the gratings, operating in the Raman Nath regime, exhibit a morphology and a electro-optical behavior that are typical of the POLICRYPS gratings realized by two-beam interference holography.

Abstract

In this work we present the first realization and characterizationof two-dimensional periodic and aperiodic POLICRYPS (Polymer LiquidCrystal Polymer Slices) structures, obtained by means of a single-beamholographic technique exploiting a high resolution spatial light modulator(SLM). A first investigation shows that the gratings, operating in the RamanNath regime, exhibit a morphology and a electro-optical behavior that aretypical of the POLICRYPS gratings realized by two-beam interferenceholography.
