Abstract
Reflection gratings have been recorded and investigated in H-PDLC materials by means of real-time spectroscopy during the polymerization process in view of possible application in optical data storage. High spatial frequency gratings (>6000lines/mm) with diffraction efficiency up to 45% and index modulation over 0.01 were obtained. The effects of the shrinkage of the reflection gratings has been detected showing a displacement of the reflected wavelength from the expected value of about 3.8%. Finally recording of microgratings has been carried out observing some optimal agreement between the microscopic and the macroscopic parameters.
