A new publication from Opto-Electronic Science; DOI 10.29026/oes.2022.220010 considers optical logic gates in future computers.

All-Optical Logic Gate: A device that utilises light to perform Boolean logical operations without the need for electrical conversion. Semiconductor Optical Amplifier (SOA): ...

A research team from Skoltech and the University of Wuppertal in Germany determined that an all-optical universal logic gate that was previously developed at Skoltech can operate at a speed of 240 ...

It is nice to see someone who appreciates the three requirements for logic. Amplification, Inversion and AND, or OR :) The Nand gate does all three, but still it is three parts.

This serves as the basic building block for one type of logic gate (XNOR), and the remaining types of logic gates are built by adding filters or other optical components.

These little devices take either one or two “bits” of information, a 1 or a 0, and perform a simple logical operation on them to produce either a 1 or a 0 as an output, which then feeds into the next ...

It's time to dig inside to understand how the internal CPU components are designed. We'll discuss transistors, logic gates, power and clock delivery, design synthesis, and verification.

The logic-gate networks did just as well as these other efficient methods at classifying images in the CIFAR-10 data set, which includes 10 different categories of low-resolution pictures, from ...
