Optical signals in conventional optoelectronic devices have to be converted into electronic signals when they are amplified or manipulated. But the slow pace of electrons through silicon-based ...

Transistors, the tiny switches that flip on and off inside computer chips, have long been the domain of electricity. But scientists are beginning to develop chip components that run on light. Last ...

Optical circuits use light instead of electricity, making them faster and more energy-efficient than electrical systems. Scientists have developed a first building block for photonic 'transistors' ...

Researchers in Switzerland have made the world's smallest optical transistor ever from a single dye molecule. The device, which works by weakening or amplifying a "source" laser beam depending on the ...

(Nanowerk News) Internet connections and computers need to be ever faster and more powerful nowadays. However, conventional central processing units (CPUs) limit the performance of computers, for ...
