Abstract
We present designs of all-optical ultrafast simultaneous NOR logic gate/Half-Adder/Subtractor, Full-Adder/Subtractor and Multiplexer/De-Multiplexer circuits using add-drop silicon microring resonators. The proposed circuits require less number of switches and inputs for realization of the desired logic compared to earlier reported designs. Multiplexer/De-Multiplexer operations can be realized from the same circuit by simply interchanging the inputs and outputs. Lower energy consumption and delays along with reconfigurability and compactness make them attractive for practical applications.
