Researchers have designed an optical lens that exhibits two properties that so far have not been demonstrated together: self-focusing and an optical effect called the Talbot effect that creates repeating...

High-speed optical circuits and sensors generally require strict control over light polarization to minimize loss and cross-talk in photonic devices such as waveguides. An A*STAR team now predicts that noise...

Scientists have developed new 2D nanostructured surfaces that reflect light in such a way that they appear three-dimensional, conveying both shade and shadows. The surfaces can already be used for...

Brown University researchers have developed a new method of manipulating the polarization of light at terahertz frequencies. The technique uses stacks of carefully spaced metal plates to make a polarizing...

It’s hard to get an X-ray image of low-density material like tissue between bones because X-rays just pass right through like sunlight through a window. But what if you need...
