New Device Would Enable Optical and Mechanical Waves Vibrating at Tens of Gigahertz to Interact

A silicon photonic device capable of enabling the interaction of mechanical and optical waves vibrating at tens of gigahertz (GHz) has been theoretically developed by researchers at the University of Campinas's Gleb Wataghin Physics Institute (IFGW-UNICAMP) in São Paulo State, Brazil.

Applying Anderson Localization to Use Visible Light for Sensing Nanoscale Features

The reason why atoms cannot be viewed with the naked eye is that they are very tiny in relation to the wavelength of light — a good example for a common principle in optics, namely that light is insensitive to features that are considerably small relative to the optical wavelength. Yet, a new study published in the journal Science demonstrates that features even 100 times smaller than the optical wavelength can be sensed by light.

Optical Characteristics of Plasmons Unearthed

Scientists at the University of Arkansas have successfully performed a study for elucidating the optical characteristics of plasmonic nanostructures. This research can open the door for developing enhanced sensors applied in security and biomedical devices, as well as in solar cells. The Researchers from the Department of Physics recently reported the outcomes of the research in the PLOS ONE journal.

World's Thinnest Hologram Opens Door to New 3D Realm

Science fiction is filled with interactive 3D holograms. They have been used in epic movies such as Star Wars and Avatar, but the challenge for researchers is trying to turn them into reality by developing holograms that are sufficiently thin to work with advanced electronics.

Photonic Chip for Achieving Superresolution Light Microscopy

A photonic chip that enables superresolution light microscopy—or ‘nanoscopy’—to be achieved by using traditional microscopes has been developed by physicists at Bielefeld University and The Arctic University of Norway in Tromsø. In the case of nanoscopy, single fluorescent molecules’ position can be ascertained at an accuracy of a few nanometres—or one-millionth of a millimetre.

Super-Resolution Imaging Made Possible by Fabricating Hyperlens Devices

For many centuries, lens makers have worked hard to make a perfect lens with the ability to produce pristine and perfect images. In the year 1873, Ernst Abbe—a German physicist and optical scientist—found out the diffraction limit of the microscope.
