The idea of optical computing—the use of photons instead of electrons to perform computational operations—has been around for decades. However, interest has resurged in recent years; the potential for ...

Opaque materials can transmit light when excited by a high-intensity laser beam. This process, known as optical bleaching, induces a nonlinear effect that temporarily alters the properties of a ...

Increasingly complex applications such as artificial intelligence require ever more powerful and power-hungry computers to run. Optical computing is a proposed solution to increase speed and power ...

For decades there has been near constant progress in reducing the size, and increasing the performance, of the circuits that power computers and smartphones. But Moore’s Law is ending as physical ...

Research on ONNs began as early as the 1960s. To clearly illustrate the development history of ONNs, this review presents the evolution of related research work chronologically at the beginning of the ...

Subscribe to our newsletter for the latest sci-tech news updates. The research, published in Nature Communications, addresses one of the key challenges to engineering computers that run on light ...

OpenLight and Tower Semiconductor have announced a successful demonstration of a 400G/lane modulator on Tower's silicon photonics platform, PH18DA, which achieves over a 3.5dB extinction ratio using ...

Want to call someone a quick-thinker? The easiest cliché for doing so is calling her a computer – in fact, “computers” was the literal job title of the “Hidden Figures” mathematicians who drove the ...

Researchers demonstrate ultrafast multivalley optical switching in germanium (Ge) using a single-color pulse laser. This breakthrough enables precise transparency control across multiple wavelengths, ...
