Abstract : Direct formation of surface relief gratings at modest intensities on azobenzene polymers has recently been accomplished. Unusual optical erasure of these surface relief gratings was observed. It is found that the optical erasure is dependent on the polarization state of the erasing beam as well as that of the recording beams used to form the gratings. Thus, gratings when formed, memorize the polarization states which create them and influence their erasure behaviors accordingly. Direct transfer of patterns by photoprint through a phase mask has been achieved.
