Whereas conventional microchips use electrons to transmit and process information, photonic microchips utilize particles of light (photons). They can therefore process and transmit data much faster than electronic chips can, because photons can carry information at the speed of light. They also offer higher bandwidth, as different wavelengths can carry distinct data streams, and they lose less energy as heat.
Instead of metal wires, micrometer-wide channels called waveguides direct light across the photonic chip. These chips also contain wavelength splitters, spatial mode sorters and mirrors — all of which are essential for separating and directing different wavelengths and light patterns within a footprint a fraction of the width of a human hair.
The newly available on-chip space could allow engineers to "unlock new functionalities" by packing on more components, the researchers wrote in the study. Notably, the work demonstrates that AI can produce boundary-pushing chip designs that are also practical to manufacture.
The AI algorithm then worked backward, testing and refining different designs until it found the delicate nanostructures that could achieve the desired result.

Components for photonic chips typically have hand-engineered designs. Engineers start with a tried-and-true design and painstakingly optimize it for new performance parameters. On top of being slow, this method limits the range of device geometries that can be explored.
The resulting mirrors, which are about 11 μm long, reflected up to 98.5% of incoming light while blocking unwanted light patterns. When placed in pairs on each side of a waveguide, the light bounced between them over 100 times before escaping, demonstrating the silicon nitride's low losses, the scientists explained.
AI-designed chips edge closer to real-world use
While the researchers have successfully demonstrated these compact components individually, they have not combined the components into a complete integrated optical circuit yet. Achieving this will be the next step toward building fully functional photonic chips that harness the increased component density enabled by these designs.

Some systems can even generate effective chip designs from a 200-word prompt. Google's AlphaChip, a machine learning method that designs chip layouts, has produced "superhuman" floor plans that have been deployed in the tech giant's production AI chips.
