Topological insulators are key to bending light around tight corners in tiny spaces with low back-scattering loss, according to engineers at Duke University in the US. The rectangular device is 35 x 5.5μm – said to be 100x smaller than previously demonstrated ring-resonators. By carefully controlling the geometry of a crystal lattice the researchers blocked ...
