Abstract :
In previously proposed ORGAs, the optical reconfiguration period was designed to be constant by assuming a worst-case reconfiguration speed. However, the diffraction efficiency of a holographic memory differs depending on the number of bright bits included in a configuration context. Therefore, previous ORGAs can not fully exploit reconfiguration performance. For that reason, this paper presents a proposal for an analog reconfiguration-period adjustment technique for ORGAs to reduce each reconfiguration period. The advantages are then discussed herein based on experimental results obtained using an ORGA system on which the technique is adopted.
