If you are reading this on your smartphone, its CPU (central processing unit) is running at its full speed. It is a tiny chip containing billions of the more basic units called logic gates. In the ...

All-optical logic gates constitute a pivotal advancement in photonic computing, where Boolean operations are executed entirely by light rather than by electrical signals. This technology exploits ...

Optical logic gates represent a cutting‐edge approach to perform computation entirely with light, bypassing the limitations inherent to electronic components. By exploiting light’s phase, intensity, ...
