Alcatel-Lucent Claims New Undersea Speed Record – 31TB/s

We’re still in the early stages of 100G deployment, but the next wave of technology is hitting the testing and demo stage. Alcatel-Lucent today claimed a new world record for highest subsea capacity over a single fiber, putting a whopping 31 Tbps over a 7200km link.

3D+2D Television Allows for Simultaneous 3D and 2D Watching

3D Display with no Ghosting

Engineers at UC Santa Cruz have developed a 3D+2D television that that combines both 2D and 3D, allowing viewers with stereo glasses to see three-dimensional images, while viewers without the glasses see a normal two-dimensional image without blurriness.

With existing 3D television displays, viewers must wear stereo glasses to get the effect of seeing images on the screen in three dimensions, while viewers without the glasses see a blurry image. Continue reading “3D+2D Television Allows for Simultaneous 3D and 2D Watching” »

Lithuanian business: no technology design without physicists

v jokuzis 4837

Like every year, during the peak of accessions to the universities, graduates are overloaded with advices: what studies to choose, and what perspectives and disappointments await after selecting certain study fields. As a rule, experts in mass media continue to repeat that social sciences offer the least perspectives, while the most promising areas are considered to be engineering, medicine, and biotechnologies.

The Parallella project will make parallel computing accessible to everyone

epifani large

Project Goals: Making parallel computing easy to use has been described as “a problem as hard as any that computer science has faced”. With such a big challenge ahead, we need to make sure that every programmer has access to cheap and open parallel hardware and development tools.

Graphene Speeds Telecommunication

Graphene Faster

Research from the Universities of Bath and Exeter suggests that the use of graphene in telecommunications could improve speeds by nearly a hundred times that of current materials.

In a paper published in Physical Review Letters, researchers from the Center for Graphene Science at the Universities of Bath and Exeter have demonstrated for the first time incredibly short optical response rates using graphene, which could pave the way for a revolution in telecommunications.

New 5D technology for “eternal” data storage


A research group in Britain has recorded data into a crystal of nanostructured glass. This future storage with practically unlimited lifetime and capacity exceeding Blu-Ray’s by 2,800 times might save civilization’s data for aliens if humankind is gone. Continue reading “New 5D technology for “eternal” data storage” »

A New Way to Trap Light: Phenomenon Could Lead to New Types of Lasers and Sensors

There are several ways to "trap" a beam of light -- usually with mirrors, other reflective surfaces, or high-tech materials such as photonic crystals. But now researchers at MIT have discovered a new method to trap light that could find a wide variety of applications.

Entanglement Enhanced Detection of Single Photons

Detection of Single Photons

In a newly published study, physicists from the University of Innsbruck detail a technique to detect the scattering of a single photon on a broad optical transition with high sensitivity, using an entangled state to amplify the tiny momentum kick an ion receives upon scattering a photon.

Metal–oxide–semiconductor field-effect transistor with a vacuum channel

Electrons emitted from the interface of oxide and silicon

With physical barriers limiting further increases in semiconductor electronic efficiency, scientists at the University of Pittsburgh redesigned the structure of the vacuum electronic device, allowing electrons to travel ballistically in a nanometer-scale channel without any collisions or scattering.

All-optical transistor


Optical computing — using light rather than electricity to perform calculations — could pay dividends for both conventional computers and quantum computers, largely hypothetical devices that could perform some types of computations exponentially faster than classical computers. An optical switch that can be turned on by a single photon could point toward new designs for both classical and quantum computers.

Graphene Provides Cooling for Electronics

producing semiconductors from graphene

A new discovery shows that graphene provides efficient electronics cooling, reducing the working temperature in hotspots inside a processor by up to 25 percent.

An international group of researchers, headed by Chalmers University of Technology in Sweden, are the first in the world to show that graphene has a heat dissipating effect on silicon based electronics. Continue reading “Graphene Provides Cooling for Electronics” »

Transistors without Semiconductors


By placing nanometer sized quantum dots of gold across on the tops of the boron nitride nanotubes, researchers at Michigan Tech created a quantum-tunneling device that acts like a transistor at room temperature without using semiconducting materials.
For decades, electronic devices have been getting smaller, and smaller, and smaller. It’s now possible—even routine—to place millions of transistors on a single silicon chip.

Here’s how to fit 1,000 terabytes on a DVD

ncomms3061 f1

We live in a world where digital information is exploding. Some 90% of the world’s data was generated in the past two years. The obvious question is: how can we store it all? In Nature Communications today, we, along with Richard Evans from CSIRO, show how we developed a new technique to enable the data capacity of a single DVD to increase from 4.7 gigabytes up to one petabyte (1,000 terabytes).
