Breakthrough nanodisk pushes photonic research forward

Researchers at Chalmers University of Technology, in Sweden, have for the first time succeeded in combining two major research fields – nonlinear and high-index nanophotonics – in a single disk-like nanoobject. Since the object is a thousand times thinner than the human hair, yet very powerful, the breakthrough has great potential in the development of efficient and compact nonlinear optical devices. “My feeling is that this discovery has a great potential,” says Professor Timur Shegai, who led the study at Chalmers.
