Scientists have demonstrated that negative refraction can be achieved using atomic arrays -- without the need for artificially manufactured metamaterials. Scientists have long sought to control light ...

Refraction—the bending of light as it passes through different media—has long been constrained by physical laws that prevent independent control over how light waves along different directions bend.

3D printing and silicon photonics have combined in a rather exciting way this week. Researchers at MIT have engineered a novel 3D printing design on a single computer chip, officially the world's ...
