Asynchronous optical bus for optical VLSIs

Recently, optically reconfigurable gate arrays consisting of a holographic memory, a laser array, and an optically reconfigurable gate array VLSI have been under development as high-speed dynamic reconfigurable devices. High-speed dynamic reconfiguration of optically reconfigurable gate arrays can be achieved using a two-dimensional optical bus. If such high-speed reconfiguration were feasible, then its programmable gate array performance could be increased dramatically. This paper presents a demonstration of high-speed asynchronous optical dynamic reconfiguration based on an optically reconfigurable gate array VLSI. The reconfiguration speed of the optically reconfigurable gate array can reach 206.44 Gbit/s.
