Logic elements “Exclusive OR” are widely used in a variety of digital devices. However, in some cases, for example, when using increased operating voltages, the use of standard chips is impossible.

The possibility of creating passive and active optoelectronic logic elements simultaneously performing the functions AND, NAND, OR, NOR, XOR, XNOR is considered. Passive logic elements, unlike active ...

Researchers at Politecnico di Milano and CNR-IFN have demonstrated all-optical logic operations in a tungsten disulfide (WS₂) monolayer at rates as high as 10 terahertz, according to a study published ...
