A new publication from Opto-Electronic Science; DOI 10.29026/oes.2022.220010 considers optical logic gates in future computers. If you are reading this on your smartphone, its CPU (central ...

In the very distant future, this could one day form the basis for new photonic logic gates and microchips. More information: Heyou Zhang et al, Purely Optical, Reversible, Read‐Write‐Erase ...

Get Instant Summarized Text (Gist) An all-optical universal logic gate based on polariton condensates operates at 240 GHz at room temperature, significantly surpassing electronic counterparts. The ...

Light-based logic: The optical chirality logic gate is made of a nonlinear optical material that generates an output signal that’s dependent on the chirality of the two input beams. (Courtesy: Yi ...

The paper outlines “Miller’s criteria” for practical optical logic gates. In particular, any optical scheme must provide outputs suitable for introduction to another gate’s inputs and also ...

Traditional chips work by ferrying electrons, but Yi Zhang at Aalto University, Finland, and his colleagues have managed to create optical logic gates that perform the same functions with light.

So how can we build different types of logic gates using optics? As the simplest way of implementing optical logic gates, spatial coding of optical field has been proposed very early in the 1970s and ...

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 ...
