Achromatic Flat Lenses Add More Color to the World of Optics

A new, flat lens with the ability to focus light with a higher efficiency within the visible spectrum was reported by a team of researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) last summer. In order to bend and focus light as it passed, an ultrathin array of nanopillars was used in the lens.

Unique Properties of Graphene Could Revolutionize Photonic and Opto-Electronic Devices

The importance of graphene can hardly be overstated. Graphene is the thinnest material comprised of atoms. It is only one atomic layer thick and hence an almost ideal representation of a two-dimensional material in our three-dimensional world.

New Technology Allows Multispectral Printing and Imaging

Researchers at Duke University believe that they have conquered a longstanding obstacle in producing cheaper, more robust processes to print and image spanning a range of colors extending into the infrared. There are a broad range of "colors" across the electromagnetic spectrum that humans cannot see, but will provide a wealth of information.

Researchers Develop Silicon Nanoantenna that Scatters Light in Particular Direction

A group of physicists from the Moscow Institute of Physics and Technology (MIPT), ITMO University, and The University of Texas at Austin have created a unique nanoantenna with the ability to scatter light in a specific direction based on the intensity of incident radiation. The outcomes of this research will help develop flexible processing of optical information in telecommunication systems.
