Production of photonic chips via molecular beam epitaxy

By Niels Bohr Institute

The special machine, which is the heart of the new facility, specializes in making photonic chips – i.e. light-based chips – which constitute the future solution within high-speed communication, optical data processing and also photonic quantum circuits. The method used by the machine is called molecular beam epitaxy, and it makes it possible to deposit extremely thin layers of atoms on the wafers with enormous precision and purity. And it is precisely this precision and purity that makes it possible to also produce quantum chips on the machine.
