It looks like a team of UC Berkeley researchers led by mechanical engineering professor Xiang Zhang (pictured) have found a way to squeeze light into tighter spaces than ever though possible, which they say could lead to breakthroughs in the fields of optical communications, miniature lasers, and optical computers.
The key to this new technique, it seems, is the use of a “hybrid” optical fiber consisting of a very thin semiconductor wire placed close to a smooth sheet of silver, which effectively acts as a capacitor that traps the light waves in the gap between the wire and the metal sheet and lets it slip though spaces as tiny as 10 nanometers (or more than 100 times thinner than current optical fibers).
That’s apparently as opposed to previous attempts that relied on surface plasmonics, in which light binds to electrons and allows it to travel along the surface of metal, which only proved effective over short distances.
While all of this is still in the theoretical stage, the researchers seem to think they’re on to something big, with research associate Rupert Olten saying that this new development “means we can potentially do some things we have never done before.
SAN FRANCISCO (Reuters) – Three tech giants — Hewlett-Packard, Intel and Yahoo — said on Tuesday they are teaming up on a research project to help turn Web services into reliable, everyday utilities.
The companies are joining forces with academic researchers in Asia, Europe and the United States to create an experimental network that lets researchers test “cloud-computing” projects — Web-wide services that can reach billions of users at once.
Their goal is to promote open collaboration among industry, academic and government researchers by removing financial and logistical barriers to working on hugely computer-intensive, Internet-wide projects.
Founding members of the consortium said they aim to create a level playing field for individual researchers and organizations of all sizes to conduct research on software, network management and the hardware needed to deliver Web-wide services as billions of computer and phone users come online.
“No one institution or company is going to figure this out,” said Prabhakar Raghavan, the head of Yahoo Research who is also a consulting professor of computer science at nearby Stanford University.
Cloud computing has become the industry’s biggest buzzword. It is a catch-all term to describe how Internet-connected hardware and software once delivered as discreet products can be managed as Web-based, utility-like services.
“Potentially the entire planet will come to rely on this, like electricity,” Raghavan said, referring to the push to make everything from daily communications to shopping to entertainment into always-available, on-demand Web services.
“We are all trying to move from the horse driving the wagon to a million ants driving the wagon,” Raghavan said of the need to let computers manage millions of small jobs, adding that the available capacity on the Web would vary widely. “The challenge can be a billion ants one day and a million ants the next.” Continued…
