Optical Data Storage Dips Below the Diffraction Limit
NEW YORK, Dec. 6, 2023 — Physicists at The City College of New York (CCNY) have developed a technique with the potential to enhance optical data storage capacity in diamonds. This is possible by multiplexing the storage in the spectral domain. “It means that we can...
Laser-Writing Method Supports Long-term 5D Optical Data Storage
SOUTHAMPTON, England, Nov. 1, 2021 — University of Southampton researchers have developed a fast and energy-efficient laser-writing method for producing high-density nanostructures in silica glass. The resulting tiny structures can be used for long-term five-dimensional (5D) optical...
Metasurface Tech Allows for More Efficient Optical Storage
WEST LAFAYETTE, Ind., Feb. 4, 2021 — Researchers at Purdue University have developed a technology that aims to replace Morse code with colored “digital characters,” helping to modernize optical storage media. The advancement, the researchers said, will help with the...
Chip-based Frequency Comb Sharpens Neural Networks
MÜNSTER, Germany, Jan. 11, 2021 — Through an international collaboration, researchers from the University of Münster have developed photonic processors that combine processing and data storage on a single chip. Led by Wolfram Pernice, a professor at the Institute of Physics and...
Light Stored and Transported in a Cloud of Atoms
MAINZ, Germany, Oct. 21, 2020 — Researchers at Johannes Gutenberg University Mainz (JGU) successfully transported light stored in a quantum memory over a distance of 1.2 mm. The technology, once refined, could have implications for quantum memory storage. To achieve high-level...
Tuned Resonators Allow Control of Electromagnetically Induced Transparency
ST. LOUIS, Jan. 16, 2020 — Researchers at Washington University in St. Louis have devised an optical resonator system that can be used to turn transparency on and off. The ability to manipulate electromagnetically induced transparency (EIT) without the introduction of an...
Liquid Crystal Matrix Slows Light to 1 Billionth of its Speed
NICE, France, and XIAMEN, China, Aug. 14, 2013 — Light can be slowed to less than a billionth of its top speed by using embedded dye molecules in a liquid crystal matrix, which could lead to new technologies in remote sensing and measurement science. Taking advantage of light’s travel as a...
Honor Cites Blue LED Creator’s Inventions, IP Protection Efforts
SANTA BARBARA, Calif., Oct. 10, 2012 — Shuji Nakamura was honored recently as the 2012 Inventor of the Year by the Silicon Valley Intellectual Property Law Association for his inventions, which include the blue LED, as well as his intellectual property protection efforts.
Helios Brings Silicon Photonics Fabrication to EU Companies
Sep 1, 2012 — Being able to manufacture optical components within the CMOS processing infrastructure is key to realizing the potential of silicon photonics. Photonics is a rapidly growing sector in the global economy. Optical communications, optical...
Holographic Material Stores 20 Blu-rays on 1 Disc
NISKAYUNA, N.Y., July 20, 2011 — A new microholographic material can support data recording at the same speed as Blu-ray discs but with 10 times their typical storage capacity.
Light Dragged by Slowing It to Speed of Sound
GLASGOW, Scotland, July 7, 2011 — For the first time, light has been slowed to the speed of sound using a technique that could improve optical storage and the processing of quantum information. Scientists at the University of Glasgow dragged light through various substances,...
Laser breakthrough could soon enable 1-TB optical storage
SENDAI, Japan – Numerous research labs are looking for ways to increase the amount of information one can store on a CD-ROM or related optical disc, but the equipment needed to push past the boundaries of Blu-ray technology is exceedingly large and expensive....
BOB Laser Offers Variety of Laser Modules and Diodes
Aug 30, 2010 — Am sure you have seen lasers. Here's a supplier: BOB Laser Co. Ltd., a supplier from Hua Du District, Guangzhou, from Mainland China. BOB has set up three production lines: laser diode and photodetector packaging, optical transceivers and...
OSA to Launch New Journal
WASHINGTON, DC, June 7, 2010 — The Optical Society (OSA) announced it will launch a new journal devoted to optical materials, called Optical Materials Express (OME). OME will launch in spring 2011 with bi-monthly issues, joining OSA's portfolio of 14 peer-reviewed optics...
Holographic disc can store 100 DVDs
NISKAYUNA, N.Y. – GE Global Research, the technology development unit of General Electric, has created a disc that is the size of a standard DVD yet can hold the equivalent of 100 DVDs’ worth of information. The disc contains holograms similar to those you might...
