#Better memory with faster lasers DVDS and Blu-ray disks contain so-called phase-change materials that morph from one atomic state to another after being struck with pulses of laser light, with data"recorded"in those two atomic states.
Using ultrafast laser pulses that speed up the data recording process, Caltech researchers adopted a novel technique, ultrafast electron crystallography (UEC),
In doing so, they discovered a previously unknown intermediate atomic state--one that may represent an unavoidable limit to data recording speeds.
By shedding light on the fundamental physical processes involved in data storage the work may lead to better, faster computer memory systems with larger storage capacity.
The research, done in the laboratory of Ahmed Zewail, Linus Pauling Professor of Chemistry and professor of physics, will be published in the July 28 print issue of the journal ACS Nano.
These two states represent 0s and 1s of digital data.""Today, nanosecond lasers--lasers that pulse light at one-billionth of a second--are used to record information on DVDS and Blu-ray disks,
by driving the material from one state to another, "explains Giovanni Vanacore, a postdoctoral scholar and an author on the study.
The speed with which data can be recorded is determined both by the speed of the laser--that is,
--and to how fast data can be recorded, regardless of the laser speeds used.""Even if there is a laser faster than a femtosecond laser,
"Despite revealing such limits, the research could one day aid the development of better data storage for computers,
Right now, computers generally store information in several ways, among them the well-known random-access memory (RAM) and read-only memory (ROM.

whenever the computer is powered down. ROM storage, including CDS and DVDS, uses phase-change materials and lasers to store information.
Although ROM records and reads data more slowly, the information can be stored for decades. Finding ways to speed up the recording process of phase-change materials
and understanding the limits to this speed could lead to a new type of memory that harnesses the best of both worlds.

#Computing at the speed of light University of Utah engineers have taken a step forward in creating the next generation of computers
and mobile devices capable of speeds millions of times faster than current machines. The Utah engineers have developed an ultracompact beamsplitter--the smallest on record--for dividing light waves into two separate channels of information.
and shuttle data with light instead of electrons. Electrical and computer engineering associate professor Rajesh Menon and colleagues describe their invention today in the journal Nature Photonics Silicon photonics could significantly increase the power and speed of machines such as supercomputers
data center servers and the specialized computers that direct autonomous cars and drones with collision detection. Eventually, the technology could reach home computers
and mobile devices and improve applications from gaming to video streaming.""Light is the fastest thing you can use to transmit information,
"says Menon.""But that information has to be converted to electrons when it comes into your laptop.
In that conversion, you're slowing things down. The vision is to do everything in light.""Photons of light carry information over the Internet through fiber-optic networks.
But once a data stream reaches a home or office destination, the photons of light must be converted to electrons before a router
or computer can handle the information. That bottleneck could be eliminated if the data stream remained as light within computer processors."
"With all light, computing can eventually be millions of times faster, "says Menon. To help do that, the U engineers created a much smaller form of a polarization beamsplitter
(which looks somewhat like a barcode) on top of a silicon chip that can split guided incoming light into its two components.
Before, such a beamsplitter was over 100 by 100 microns. Thanks to a new algorithm for designing the splitter,
Menon's team has shrunk it to 2. 4 by 2. 4 microns, or one-fiftieth the width of a human hair and close to the limit of what is physically possible.
The beamsplitter would be just one of a multitude of passive devices placed on a silicon chip to direct light waves in different ways.
By shrinking them down in size, researchers will be able to cram millions of these devices on a single chip.
mobile devices such as smartphones or tablets built with this technology would consume less power, have longer battery life
and generate less heat than existing mobile devices. The first supercomputers using silicon photonics--already under development at companies such as Intel
and IBM--will use hybrid processors that remain partly electronic. Menon believes his beamsplitter could be used in those computers in about three years.
Data centers that require faster connections between computers also could implement the technology soon, he says s
