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' ...

A component that could lead to the first practical all-optical transistor has been created by researchers in Ireland. Optical transistors control one beam of light using another beam and are analogous ...

Physicists from the Department of Nanophotonics and Metamaterials at ITMO University have experimentally demonstrated the feasibility of designing an optical analog of a transistor based on a single ...

Researchers from ETH Zurich have recently managed to create an optical transistor from a single molecule in what is yet another important achievement on the road to quantum computing. Quantum ...
