Abstract

This paper demonstrates the circuit design of an electro-optic full adder based on silicon micro-ring resonator as its core component. The ring resonator design incorporates the carrier-injection forward-biased PIN waveguide structure for its logical operation. This work also provides the working principle of the designed full adder. It also proceeds with the demonstration and analysis of the operation with two digital input bits information together with a Carry-In (CIN) bit input injected at 1 Gbps, and the output generated as SUM output as well as Carry-Out (COUT) both at the same data rate generated. The performance of the proposed circuit design is verified by clear output timing waveforms, following the sequence of the digital full adder logic table.
