IBM using light instead of wires for building supercomputers-on-a-chip

IBM's optical modulator performs the function of converting a digital
electrical signal carried on a wire, into a series of light pulses, carried
on a silicon nanophotonic waveguide. First, an input laser beam (marked by
red color) is delivered to the optical modulator. The optical modulator
(black box with IBM logo) is basically a very fast "shutter" which controls
whether the input laser is blocked or transmitted to the output waveguide.
When a digital electrical pulse (a "1" bit marked by yellow) arrives from
the left at the modulator, a short pulse of light is allowed to pass through
at the optical output on the right. When there is no electrical pulse at the
modulator (a "0" bit), the modulator blocks light from passing through at
the optical output. In this way, the device "modulates" the intensity of the
input laser beam, and the modulator converts a stream of digital bits ("1"s
and "0"s) from electrical input pulses into pulses of light. Credit: IBM
Supercomputers that consist of thousands of individual processor "brains"
connected by miles of copper wires could one day fit into a laptop PC,
thanks in part to a breakthrough by IBM scientists announced today.
And while today's supercomputers can use the equivalent energy required to
power hundreds of homes, these future tiny supercomputers-on-a-chip would
expend the energy of a light bulb.

 In a paper published in the journal Optics Express, the IBM researchers
detailed a significant milestone in the quest to send information between
multiple cores -- or "brains" -- on a chip using pulses of light through
silicon, instead of electrical signals on wires.

The breakthrough -- known in the industry as a silicon Mach-Zehnder
electro-optic modulator -- performs the function of converting electrical
signals into pulses of light. The IBM modulator is 100 to 1,000 times
smaller in size compared to previously demonstrated modulators of its kind,
paving the way for many such devices and eventually complete optical routing
networks to be integrated onto a single chip. This could significantly
reduce cost, energy and heat while increasing communications bandwidth
between the cores more than a hundred times over wired chips.

"Work is underway within IBM and in the industry to pack many more computing
cores on a single chip, but today's on-chip communications technology would
overheat and be far too slow to handle that increase in workload," said Dr.
T.C. Chen, vice president, Science and Technology, IBM Research. "What we
have done is a significant step toward building a vastly smaller and more
power-efficient way to connect those cores, in a way that nobody has done
before."

Today, one of the most advanced chips in the world -- IBM's Cell processor
which powers the Sony Playstation 3 -- contains nine cores on a single chip.
The new technology aims to enable a power-efficient method to connect
hundreds or thousands of cores together on a tiny chip by eliminating the
wires required to connect them. Using light instead of wires to send
information between the cores can be 100 times faster and use 10 times less
power than wires.

"We believe this is a major advancement in the field of on-chip silicon
nanophotonics," said Dr. Will Green, the lead IBM scientist on the project.
"Just like fiber optic networks have enabled the rapid expansion of the
Internet by enabling users to exchange huge amounts of data from anywhere in
the world, IBM's technology is bringing similar capabilities to the computer
chip."

IBM's optical modulator performs the function of converting a digital
electrical signal carried on a wire, into a series of light pulses, carried
on a silicon nanophotonic waveguide. First, an input laser beam is delivered
to the optical modulator, which acts as a very fast "shutter" which controls
whether the input laser is blocked or transmitted to the output waveguide.
When a digital electrical pulse arrives from a computer core to the
modulator, a short pulse of light is allowed to pass through at the optical
output. In this way, the device "modulates" the intensity of the input laser
beam, and the modulator converts a stream of digital bits ("1"s and "0"s)
from electrical signals into light pulses.

The report on this work, entitled "Ultra-compact, low RF power, 10 Gb/s
silicon Mach-Zehnder modulator" by William M. J. Green, Michael J. Rooks,
Lidija Sekaric, and Yurii A. Vlasov of IBM's T.J.WatsonResearch Center in
Yorktown Heights, N.Y. is published in Volume 15 of the journal Optics
Express. This work was partially supported by the Defense Advanced Research
Projects Agency (DARPA) through the Defense Sciences Office program
"Slowing, Storing and Processing Light".

Yep...

I've been sending messages to the president of AMD, saying they need to 
develop a Photonic processor (Optical Computing).

There's lots of universities doing research on this...

Nope... Nope... Nope... you remember what the alien abductees said about the 
aliens don't you???
Remember what the aliens said when we advised the WE have computers and the 
aliens said they're computers put our computers to shame.

HUH?

They said the aliens have computers, but they're computers are made "one 
molecule at a time."
They calculate things linearly...
They have qbits and DARPA's funding nanotechnology which is going to get the 
US (earth) there.
QUANTUM COMPUTERS are the aliens computers.  Because their UFO's are made 
one molecule at a time - NANOTECHNOLOGY!

And DARPA is funding one thing and not funding another...
Because DARPA has UFO's...

IBM, INTEL and AMD - they're all doing to do the same thing... INTEL just 
brought out the 45 nm Hafnium Oxide chips.
