Some of the functions, like NOT, OR ... allows different logic gates to be wired together with patch cables. While [David] first thought to use 74-series logic circuits directly, a much more ...

Contemporary logic circuits use MOSFETs as the elements ... You guessed it, diodes can also be used to build logic gates, but not all of them, only the AND and OR gates can be built using diodes ...

A research team from Skoltech and the University of Wuppertal in Germany determined that an all-optical universal logic gate ...
