Multi-context optically reconfigurable gate array using a polymer-dispersed liquid crystal holographic memory

Optically reconfigurable gate arrays (ORGAs) have been developed as a type of multi-context field programmable gate array. Although many configuration contexts can be stored on an ORGA device and although its gate array can be reconfigured dynamically in an extremely short time, many laser sources are necessary to address the configuration contexts. Therefore, up to now, a laser reduction method on ORGAs using a polymer-dispersed liquid crystal holographic memory has been proposed. Under the ORGA, all configuration contexts can be addressed by half the number of lasers as there are reconfiguration contexts. This paper presents the results of the first demonstration of a multi-context ORGA using a polymer-dispersed liquid crystal holographic memory.
