Optically reconfigurable gate arrays (ORGAs) have been developed to realize large virtual gates and to increase gate array performance. Since the performance of gate arrays in dynamically reconfigurable gate arrays can be increased as increasing its reconfiguration clock frequency, a high-speed reconfiguration capability is extremely important. However, the efficiency of a conventional optical configuration is not good because the optical configuration speed suffers from the photodiode characteristic variation, optical component variation, alignment errors, and holographic memory properties. This paper therefore presents a proposal of a compensation method using an analog configuration context that can improve the optical configuration efficiency. Based on the experimental results, this paper presents a discussion of its performance.
