Abstract:The adder is a highly fundamental part of the central processing unit. The carry lookahead adder (CLA) has become the fastest adder used in digital circuits. For high-speed operations, optical computing has become an essential research field. In this manuscript, a microring resonator (MRR)-based all-optical (AO) CLA is proposed and analyzed. The MRR-based AO design is capable of getting a higher operational speed to fulfill the demands of end users. The Z domain's mathematical model of the CLA is developed usi… Show more
