(Phys.org)—Researchers have fabricated a silicon optical antenna that is somewhat like an extremely small, special kind of prism. This is because when a red light shines on the optical antenna, the light turns right, but ...
In principle, nothing that enters a black hole can leave the black hole. This has considerably complicated the study of these mysterious bodies, which generations of physicists have debated since 1916, when their existence ...
Researchers from the University of Southampton (UK), and the Institut d'Optique in Bordeaux (France) have devised a new approach for controlling light in a silicon chip by bringing the concept of spatial light modulation ...
Miniaturization is the magic word when it comes to nanomagnetic devices intended for use in new types of electronic components. Scientists from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have proposed the use of ion ...
(Phys.org)—Holograms have a wide variety of applications, from 3D displays to data storage, but the potential applications are currently limited by the complexity and cost of hologram fabrication. In an attempt to simplify ...
An international collaboration has succeeded in using synchrotron light to detect and record the complex 3-D magnetization in wound magnetic layers. This technique could be important in the development of devices that are ...
Describing the universe requires fewer dimensions than we might think. New calculations show that this may not just be a mathematical trick, but a fundamental feature of space itself.
The major limitation of microscopy is light itself: if we want to see an object smaller than the wavelength of visible light, we cannot use conventional optics. When it comes to imaging cells, the problems compound, since ...
Some physical principles have been considered immutable since the time of Isaac Newton: Light always travels in straight lines. No physical object can change its speed unless some outside force acts on it.
A new semiconductor laser developed at Yale has the potential to significantly improve the imaging quality of the next generation of high-tech microscopes, laser projectors, photolithography, holography, and biomedical imaging.
