«Engineers make sound loud enough to bend
light on a computer chip: Device could improve wireless communications systems.»
Not exact matches
The team did this by developing a memory system that accurately transfers between
light and sound waves
on a photonic microchip — the kind of
chip that will be used in
light - based
computers.
«For [
light - based
computers] to become a commercial reality, photonic data
on the
chip needs to be slowed down so that they can be processed, routed, stored and accessed,» said one of the research team, Moritz Merklein.
Instead of
light,
computers run
on electrons moving through silicon - based
chips — which, despite huge advances, are still less efficient than photonics.
Photons are faster and cooler than electrons, but no one has been able to bend useful frequencies of
light around the tight corners needed to navigate the million turns
on a
computer chip the size of a postage stamp.
For using the advantages of
light, i.e. speed and energy efficiency, also
on the small scale of
computer chips, researchers of KIT have made an important step from fundamental research towards application.
So I introduced the idea to use
light to move data
on a
computer chip.
Many of today's technologies (i.e. solid state
lighting, transistors in
computer chips, and batteries in cell phones) rely simply
on the charge of the electron and how it moves through the material.
«This could be used to scale current semiconductor technologies down to the atomic scale — lasers,
light - emitting diodes (LEDs),
computer chips, anything,» says Dr. Linyou Cao, an assistant professor of materials science and engineering at NC State and senior author of a paper
on the work.
Similar structures have been proposed to power quantum
computers and for use in other optical applications that require many tiny
light sources integrated together
on a single
chip.
To improve the efficiency of waveguides — devices that guide
light on the surface of silicon optical
computer chips — a complex balance must be struck.
These
lights can be left
on main beam and a
computer chip picking up images from the driver - assist camera above the interior mirror will blank out individual sections to avoid dazzling other road users.
But while the Radeon RX Vega M processors are meant for thinner and
lighter laptops for companies looking to cut down
on space, these new Coffee Lake
chips are designed for hardware manufacturers» top
computers (presumably with more powerful discrete graphics cards) where firepower is of chief concern.
Although there have been a few connected compact fluorescent bulbs, LEDs are much easier to turn into smart
lighting because they are based
on semiconductors, the same material as
computer chips, and the bulbs typically have a collection of
chips and other electronics inside of them.
