Demand for FPGAs that are usable under a space radiation environment is increasing daily. However, such high energy charged particles break a configuration context on an FPGA so that hardware itself is not robust in addition to software operations. On the other hand, Optically reconfigurable gate array (ORGA) architecture achieves not only high performance but also extreme robustness for such high-energy charged particles. However, the ORGA has an unallowable failure mode, which is a turn-off failure mode of Lasers on a Laser array. Therefore, this paper presents a proposal of a recovery method for the turn-off failure mode in an ORGA and presents its demonstration results.
