Photonic Topological Insulator Demonstrated

Facebook X LinkedIn Email
KESALSABA, Israel, April 17, 2013 — A device protecting the transport of light through a unique honeycomblike lattice structure of helical waveguides has demonstrated the photonic equivalent of a topological insulator. The discovery could bring us a step closer to quantum computing, the researchers say. As computers get faster and chips get denser, there is a need for smaller devices that manipulate light. However, as devices get smaller, imperfections in the fabrication processes can make light move irregularly and unpredictably. To prevent unwanted scattering from any kind of defect, researchers at Technion-Israel...Read full article
