Radiation Tolerance of Color Configuration on an Optically Reconfigurable Gate Array

Currently, research of optically reconfigurable gate arrays (ORGAs), a type of multi-context field programmable gate arrays (FPGAs), has progressed rapidly. ORGAs offer important benefits of high-speed reconfiguration, numerous reconfiguration contexts, and robust configuration. Such ORGAs always consist of a single-wavelength laser array to address configuration contexts. However, for this architecture, concerns related to its package size often arise. The laser array is large because of the large space between lasers. For that reason, the ORGA also tends to be large. Therefore, we have introduced some-wavelength lasers inside a laser array of an ORGA to decrease the laser array size. Results show that the ORGA package can be smaller. However, the dependability of color configuration has never been discussed up to now. This paper therefore presents a demonstration of the radiation tolerance of color configuration on an optically reconfigurable gate array.
