Field Programmable Gate Arrays (FPGAs) have been used widely in recent years because of their flexible reconfiguration capabilities. Moreover, demand of high-speed reconfiguration for FPGAs has been increasing. However, since reconfiguration of FPGAs cannot be increased because of the serial transfer of configuration data, new optically reconfigurable gate arrays (ORGAs) have been proposed as an alternative device to achieve high-speed reconfiguration and numerous reconfiguration contexts. However, in the ORGAs, alignment errors affect the configuration power consumption. This paper presents the relation between alignment errors of optical components and power consumption in optoelectronic devices.
