(PhysOrg.com) -- The remarkable eyes of a marine crustacean could inspire the next generation of DVD and CD players, according to a new study from the University of Bristol published today in Nature Photonics. http://www.physorg.com/news175702057.html Physics Sun, 25 Oct 2009 15:08:17 EST news175702057 (PhysOrg.com) -- Researchers at Cornell University have developed a device called a "time lens" which is a silicon device for speeding up optical data. The basic components of this device are an optical-fiber coil, laser, and nanoscale-patterned silicon waveguide. http://www.physorg.com/news173362735.html Physics Mon, 28 Sep 2009 13:19:51 EST news173362735 Physicists at UC San Diego have successfully created speedy integrated circuits with particles called "excitons" that operate at commercially cold temperatures, bringing the possibility of a new type of extremely fast computer based on excitons closer to reality. http://www.physorg.com/news173280934.html Physics Sun, 27 Sep 2009 14:36:05 EST news173280934 In the past, even modern technologies have failed to produce high-resolution fluorescence images from this depth because of the strong scattering of light. In the Nature Photonics journal, the Munich researchers describe how they can reveal genetic expression within live fly larvae and fish by "listening to light". In the future this technology may facilitate the examination of tumors or coronary vessels in humans. http://www.physorg.com/news165578271.html Physics Tue, 30 Jun 2009 10:58:52 EST news165578271 (PhysOrg.com) -- A team of physicists and engineers at Bristol University has demonstrated exquisite control of single particles of light - photons - on a silicon chip to make a major advance towards long-sought-after quantum technologies, including super-powerful quantum computers and ultra-precise measurements. http://www.physorg.com/news163427868.html Physics Fri, 05 Jun 2009 13:39:06 EST news163427868 By combining the best of two different distance measurement approaches with a super-accurate technology called an optical frequency comb, researchers at the National Institute of Standards and Technology have built a laser ranging system that can pinpoint multiple objects with nanometer precision over distances up to 100 kilometers. The novel LIDAR ("light detection and ranging") system could have applications from precision manufacturing lines on Earth to maintaining networks of satellites in perfect formation, creating a giant space-based platform to search for new planets. http://www.physorg.com/news162395437.html Physics Sun, 24 May 2009 14:51:06 EST news162395437 IMEC reports a method to integrate high-speed CMOS electronics and nanophotonic circuitry based on plasmonic effects. Metal-based nanophotonics (plasmonics) can squeeze light into nanoscale structures that are much smaller than conventional optic components. Plasmonic technology, today still in an experimental stage, has the potential to be used in future applications such as nanoscale optical interconnects for high performance computer chips, extremely sensitive (bio)molecular sensors, and highly efficient thin-film solar cells. IMEC`s results are published in the May issue of Nature Photonics. http://www.physorg.com/news160290454.html Physics Thu, 30 Apr 2009 06:09:00 EST news160290454 (PhysOrg.com) -- Thinking about getting an e-reader but not sure if you like reading the dim screen? An international collaboration of the University of Cincinnati, Sun Chemical, Polymer Vision and Gamma Dynamics has announced Electrofluidic Display Technology (EFD), the first technology to electrically switch the appearance of pigments in a manner that provides visual brilliance equal to conventional printed media. http://www.physorg.com/news160236184.html Technology Wed, 29 Apr 2009 15:03:51 EST news160236184 When photographers zoom in on an object to see it better, they lose the wide-angle perspective -- they are forced to trade off "big picture" context for detail. But now an imaging method developed by Princeton researchers could lead to lenses that show all parts of the scene at once in the same high detail. The new method could help build more powerful microscopes and other optical devices. http://www.physorg.com/news159537382.html Physics Tue, 21 Apr 2009 12:56:58 EST news159537382 In a recent publication in Nature Photonics, a joint team of researchers at CIC nanoGUNE, Donostia International Physics Center DIPC, Centro de Física de Materiales of CSIC/UPV-EHU in San Sebastian (Spain), Harvard University (USA) and the Max Planck Institute of Biochemistry in Munich (Germany) reports an innovative method for controlling light on the nanoscale by adopting tuning concepts from radio-frequency technology. http://www.physorg.com/news159427096.html Physics Mon, 20 Apr 2009 06:29:45 EST news159427096 Proteins, the work-horse molecules necessary for virtually every human action from breathing to thinking, have proved an almost ghostly presence, daring scientists to fully grasp their structure and behavior. Now, physicists at the University of Wisconsin-Milwaukee have developed powerful imaging techniques that promise to tell us much more about what proteins are and what they do, how they change shapes and how they work together in a cell. http://www.physorg.com/news158941208.html Physics Tue, 14 Apr 2009 15:20:32 EST news158941208 The next time an overnight snow begins to fall, take two bricks and place them side by side a few inches apart in your yard. http://www.physorg.com/news156349503.html Physics Sun, 15 Mar 2009 15:25:42 EST news156349503 (PhysOrg.com) -- Large, perfect diamonds are precious to almost all of us but to some scientists, it is the defects that really matter. This is because defects can form nanoscopic color centers, which play a key role in the development of both quantum computing and quantum cryptography. A research team at the Max Planck Institute for Biophysical Chemistry in Göttingen has now probed these color centers inside the crystal with unprecedented resolution using an optical microscope. Using STED microscopy, the scientists identified even densely packed color centers and determined their position inside the crystal with a precision better than 0.15 nanometers, corresponding to the dimension of an atom.
