Photonic computing needs more nonlinearity: Acoustics can help

A schematic representation of how an optoacoustic activation function can be employed between layers n − 1 and n + 1 of an all-optical multi-frequency neural network. Credit: Nanophotonics (2025). DOI: 10.1515/nanoph-2024-0513 Neural networks are one typical structure on which artificial intelligence can be based. The term “neural” describes their …

3D Printing News Briefs, January 20, 2024: FDM, LPBF, Underwater 3D Printer, Racing, & More – 3DPrint.com

We’re starting off with a process certification in today’s 3D Printing News Briefs, and then moving on to research about solute trapping, laser powder bed fusion, and then moving on to a partnership that will help advance 3D printed healthcare solutions. We’ll end things with an underwater 3D printer and …
