JDS Uniphase (NASDAQ: JDSU) (TSX: JDU ) today
announced that it has been awarded a contract to provide electro-optic
modulators for the National Ignition Facility (NIF) Project at the Lawrence
Livermore National Laboratory (LLNL). A number of
innovations have arisen from laser research as LLNL including small,
inexpensive radars for motion detectors; backup system alarms; and medical
monitors; CAD/CAM systems used in engineering; fast, hand-held biological
detection devices; and lasers for medicine and manufacturing. For additional information, please visit the RIKEN home page at

When completed in 2008, NIF is
expected to be the largest laser in the world.8 megajoules.
The Ishikawa Laboratory, in consideration of this issue , requested the
Ebisuzaki Laboratory to develop a two-dimensional FFT accelerator that makes
it possible to quickly process computationally intensive two-dimensional FFT.

The FFT accelerator performs phase retrieval 13 times faster than the
conventional system based on fastest CPU: a 1000 -repetition phase retrieval
for 1024 x1024 pixel image reconstruction is done in mere 87 seconds, while
the conventional system takes 20 minutes to do the same.

Synchrotron radiation is widely used in academic research/ industrial
applications, in fields such as materials science , earth and planetary
science, life science, environmental science, and medical applications ,
as an innovative instrument for material analysis, and is expected to
provide further advances in many other fields.

NIF is the
latest in a long line of large laser systems at LLNL dating back to the
mid-1970's built for inertial confinement fusion research. (IPFlex) today announced that they have jointly developed two-dimensional
fast Fourier transform accelerator (FFT accelerator) (1) using DAPDNA-2(2)
dynamically reconfigurable processor(3), shortening phase retrieval process by
an order of magnitude. It spends mere 87 seconds for a 1000-repetition phase
retrieval for 1024x1024 pixel image reconstruction, while conventional
CPU-based system spends more than 20 minutes to do the same. Until now, researchers had to either wait until entire sample
data was collected , or spend much time analyzing the intermediate data, before
deciding to proceed with the test. The Japan Atomic Energy Research Institute (JAERI) and
RIKEN (The Institute of Physical and Chemical Research) started construction
of SPring-8 in 1991 and completed the construction and opened the facility in
October 1997.com/

About NIF and Laser Research at LLNL

The NIF project is currently under construction at LLNL with funding from
the Department of Energy (DOE) and the National Nuclear Security
Administration.
There is a strong demand to confirm the actual images while collecting
X -ray scattering data as biological samples could be damaged upon X-ray
irradiation. The computation process was divided into four steps, each
represented as a hardware configuration on DAPDNA-2. DAPDNA -2 can change
its hardware configuration to provide the optimal circuitry for an application
on demand.

"We believe our broad portfolio of analog, digital , and custom modulators,
coupled with our industry-leading expertise in integrated optics, allow us
to meet very unique needs for our customers' mission-critical designs, such
as the NIF project ," said Mike Ricci, vice president of the Components and
Modules Group at JDS Uniphase. NIF will also have basic
science applications in such areas as astrophysics, hydrodynamics, and
material properties , and is expected to provide insight into the viability
of thermonuclear fusion as a future economic energy source. This configuration change can take place not only when the system
is designed, but also during operation, dynamically, in a single clock
cycle(6), to meet the instantaneous change in needs of applications
implemented by the system.
