Reconfigurable Optical Boolean Function Generator Based on Electro-Optical Nonlinear Dynamics

We propose an optical Boolean function generator based on an electro-optical nonlinear feedback loop. Theoretically, all possible Boolean functions with optical input and output can be implemented by passing through enough iterations. By changing the control signal, the optical circuit can be configured to any desired Boolean function without adjusting the physical setup. Optical components with high bandwidth can improve the computing speed markedly. The impact of noise on the system is considered in detail. The results show that a substantial number of reliable Boolean functions can be obtained in the presence of noise contamination. Compared with traditional optical digital computation systems, the proposed scheme exhibits a huge advantage in multifunctional computing and flexible configuration.
