“…Nevertheless, an important problem remains: simultaneously increasing the internal reconfiguration memory while maintaining the gate density is extremely difficult. For that reason, optically reconfigurable gate arrays (ORGAs) [5]- [7], [11]- [14], [21]- [23] have been developed to provide two capabilities: rapid reconfiguration and numerous reconfiguration contexts. Such optical reconfiguration architecture often uses liquid crystal spatial light modulators as a holographic memory [11]- [14], [21]- [23].…”
