Metasurface‐Based Optical Logic Operators Driven by Diffractive Neural Networks

Advances in Materials, 2023
In this paper, a novel optical logic operator based on the multifunctional metasurface driven by all‐optical diffractive neural network is reported, which can perform four principal quantum logic operations (Pauli‐X, Pauli‐Y, Pauli‐Z, and Hadamard gates).

Adaptive Optical Logic And Switching Devices

SPIE Proceedings, 1988
Tunable Optical Bistability, where a low power control beam is used to adapt the hysteresis response and the switching of optically bistable elements, is shown to occur in various systems with a bichromatic input. Some applications of this are suggested for more complex logic gates and for pattern recognition.
