SLD3132VF
Along with the increasing popularity of flat-panel high-definition TV sets,
the number of titles available in the Blu-ray Disc format has increased
and the age of this next generation optical disc has truly arrived.
Sony has now developed the SLD3132VF laser diode for Blu-ray disc players.
This new device concentrates all of Sony's blue-violet laser diode technology and is now being released as
the next generation standard model playback laser diode.

Blue-Violet Laser Diode
for Blu-ray Disc Players
Sony has already released the SLD3131 series
of products as Blu-ray disc playback laser
diodes. In the SLD3132VF of this release,
which is targeted as the next generation
standard model playback laser, Sony has
introduced a new laser structure and new laser
facet technologies that improve quality even
further over existing products, and has
optimized the chip size even further.
In this device, Sony has taken full advantage of
the mass production technologies established
up to now through the manufacture of laser
diodes for Blu-ray disc players in application
such as the Sony Computer Entertainment Inc.

and will continue to
contribute to the advance of the Blu-ray disc by
providing stable and continuing supply of blue-
violet laser diodes.

Excellent High-Temperature Operating
Characteristics and Low Noise
Since laser diodes are subject to heat from the
other components in the system in addition to
the heat they generate themselves, their
operating environment can reach high
temperatures. The blue-violet laser diode is a
critical key device in Blu-ray equipment and a
long operating lifetime and stable operation
in such environments are important.
Furthermore, low noise is also required for
practical reasons when used as an optical disc
laser.
In the product of this release, Sony achieved
stable operation and long life in high-
temperature environments up to 75°C by
optimizing the structure of the active layer.
Furthermore, Sony achieved excellent low-
noise characteristics by holding the threshold
current to a low level.
By making the SLD3132VF chip size smaller
than that previously used for playback laser
diodes, Sony succeeded in reducing costs.
There is a tendency for operating lifetimes to
become shorter as the chip size is reduced due
to, for example, increases in the device
operating temperature. Sony, however,
developed the SLD3132VF as a product that
achieves both high-quality and low-cost by
combining the optimized structure of the active
layer mentioned above with other Sony
technologies such as the new laser facet
technology. The SLD3132VF uses the 5.6 mm
diameter package that is the standard for
current laser diodes. Sony plans on adding the
SLD3132VFI, provided in a 3.8 mm diameter
package, to the lineup in the near future for use
in slim optical disc drives for IT and other
applications.
Many end customers are already enjoying
high-definition video created by Sony blue-
violet laser diodes. In this project as well,
the team members worked together as a
unit and created a device that can respond
to everyone's desires for both quality and
lower costs.
We are all committed to continuing to
provide both the superb video images
created by Blu-ray discs and the blue-violet
laser diodes that support those images.
