In the age of information, data processing and computation are essential. But current computation devices lack scalability and suffer from high carbon emissions. So researchers are constantly looking ...

Ternary optical computing systems represent an innovative leap beyond traditional binary computation by utilising three discrete logic states. This approach leverages the intrinsic advantages of ...

Computing is hitting a physical and economic wall just as generative artificial intelligence explodes in complexity and cost. The traditional trick of cramming more transistors onto silicon is running ...

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 ...

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 ...

A nanophotonic diffractive network performs morphological image processing, including dilation and erosion, purely through light propagation.

We always hear that future computers will use optical technology. But what will that look like for a general-purpose computer? German researchers explain it in a recent scientific paper. Although the ...

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 ...

A team of researchers developed “parallel optical matrix-matrix multiplication” (POMMM), which could revolutionize tensor ...

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 ...

Scheme illustration of object identification and all-optical 3D reconstruction system. (a) A contour surface image of the object can be obtained in a single processing of the system. (b) High-contrast ...
