Photonic chips can calculate the optimal shape of light to pass through an environment efficiently. These chips can work in pairs to automatically calculate the shape of a light beam. They can also produce multiple overlapping beams with different shapes. This can increase transmission capacity, which is important for next-generation wireless systems.
The research was conducted by Politecnico di Milano, Scuola Superiore Sant’Anna in Pisa, the University of Glasgow, and Stanford University. The study was published in Nature Photonics.
Photonic chips are small silicon chips that work as smart transceivers. They combine two or more photonic functions into a single chip. This makes them smaller, faster, and more energy-efficient.
Photonics is a branch of optics that involves the generation, detection, and manipulation of light. It’s closely related to quantum electronics, which deals with the theoretical part of photonics
