#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.
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.
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
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

#Mirrorlike display creates rich color pixels by harnessing ambient light (Nanowerk News) Using a simple structure comprising a mirror
researchers have developed a display technology that harnesses natural ambient light to produce an unprecedented range of colors
An article describing their innovative approach appears today in The Optical Society's new high-impact journal Optica("Continuous Color Reflective Displays Using Interferometric Absorption".
"This display technology, which could greatly reduce the amount of power used in multiple consumer electronics products,
the new design helps solve many key problems affecting mobile displays such as how to provide an always-on display function without requiring more frequent battery charging
and blue (RGB) of earlier display technologies.""We have developed an entirely new way of creating a color display,
"said John Hong, a researcher with Qualcomm MEMS Technologies, Inc. and lead author on the Optica paper."
"The incredibly efficient display is able to create a rich palette of colors using only ambient light for viewing,
"Harnessing Ambient light Typical color displays are essential yet power-hungry components of virtually every digital product with a human-machine interface, from cell phones and computers to home televisions and massive displays
engineers have been exploring ways to replace emissive technologies with displays that can reflect ambient light. Earlier attempts to create reflective light color displays,
however, presented a number of vexing problems. The designs required using three separate pixels to produce the red
green and blue of a traditional display. Though adequate for certain applications, the fact that only one-third of the incoming light can be reflected back toward the viewer in a typical reflective RGB format limits the gamut of colors and brightness of the display.
The new display reported in Optica is able to overcome these hurdles by reflecting more of the incoming light
and enabling the full spectrum of visible light to be displayed, including bright white and deep black.
Extending Power and Saving Energy Depending on how the display is used, the power savings can exceed current backlit technologies tenfold.
