Optically Differential Reconfigurable Gate Array Using an Optical System with VCSELs

Optically reconfigurable gate arrays (ORGAs) have been developed to allow rapid reconfiguration. We have developed an optically differential reconfigurable gate array (ODRGA) to realize fast and arbitrary partial reconfiguration capabilities. This paper presents the structure of a fabricated ODRGA-VLSI chip using an optical system with vertical cavity surface emitting lasers (VCSELs) along with experimental results of reconfiguration
