When an optical pulse train is delivered, two-photon absorption (TPA)-induced pumping causes considerable and quick gain and phase shifts in the carrier reservoir semiconductor optical amplifier ...

The previous article examined the concept of logic gates. They can be made from discrete and active electronic components, although today logic gates are available within integrated circuits. In this ...

In the early digital era, logic gates were made exclusively of transistors and discrete components. The obvious occupation of a large space and increased heat dissipation pushed technology to ...

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 processing ...

A research team from Skoltech and Bergische Universität Wuppertal in Germany has created a universal NOR logical element (from NOT—a negation operator and OR—a disjunction operator). According to the ...

Samsung Electronics has implemented three-dimensional (3D) stacked transistor technology to overcome the miniaturization ...
