A chip roughly the size of a fingernail can take a single mixed stream of light and sort it into separate, clean beams, Phys.org reported on Tuesday, November 3, 2026. The work points to a way of handling light on a very small scale.
According to Phys.org, the device untangles light that arrives as a blend of different components and outputs it as distinct beams. The report describes the chip by its small footprint, emphasizing that the light-sorting function is packed into a tiny piece of hardware.
The report did not include the full technical details of the device, and Phys.org's summary gives only the headline result. As a result, specifics such as the materials used, the range of light wavelengths handled, or the efficiency of the separation are not available from the material provided.
The result fits into a broader push toward photonic hardware, in which light rather than electric current carries and processes signals. Phys.org frames the chip's value around its size, suggesting that light-manipulating components may be shrinking toward the scale of other modern electronics.
What to watch next: whether the research team publishes fuller performance data and whether the approach can be reproduced or scaled beyond a single laboratory demonstration.
