Abstract

Optically reconfigurable gate arrays (ORGAs) with an amplitude-modulation type holographic memory have been developed as a type of multi-context field programmable gate array. The ORGA's programmable gate array can be reconfigured in nanosecond-order, with more than 100 reconfiguration contexts. However, the diffraction efficiency of the amplitude-modulation type holographic memory is not good because the holographic memory decreases its transmission light intensity depending on the modulation level. About half of the power of the laser is consumed by the holographic memory. Therefore, this paper presents a high-speed - low-power optical configuration capability of an ORGA with a phase-modulation type holographic memory.
