Abstract
We propose a new design of all-optical circuit using microring and nanoring devices, in which the simultaneous operation of half adder/subtractor arithmetic can be formed by using the dark-bright soliton conversion control within the system. The input logic "0" and "1" are performed by using dark and bright soliton pulses, respectively. By using the dark-bright soliton conversion behavior with in the π/2 phase shift device (i.e., an optical coupler), the arithmetic unit can perform simultaneously at the drop- and through- ports, respectively. In application, the proposed concept can be recognized as a simple and flexible scheme for performing the logic switching system, which can be used for advanced logical system.
