Abstract

Holographic polymer-dispersed liquid crystal (HPDLC) memory formed by a subwavelength grating (SWG) mask is presented for new optical information processing. The SWG structure in a photomask is formedonthe SiO₂ plate using the anisotropic reactive ion etching technique. The configuration contexts for optically reconfigurable gate arrays (ORGAs) are stored in the HPDLC memory by polarization modulation property basedonthe form birefringenceofthe SWG plate. The configuration context patterninthe HPDLC memory is reconstructed to write it for the ORGAs under parallel programmability.
