Outline of Final Research Achievements

All-optical logic circuits, which enable logic operations on optical digital signals in the optical domain, are expected to play an important role in the next generation of optical computing technology, which will radically accelerate processing speed. In this study, we constructed a reconfigurable all-optical logic circuit that can selectively operate various logic operations such as AND, OR, and NOT by controlling parameters such as input optical signal power and optical filter characteristics with low-speed electrical signals in an all-optical logic circuit consisting of the same circuit, and demonstrated the effectiveness of this circuit. The effectiveness of the circuit was demonstrated through demonstration experiments.
