Optical Pickup Chipset with Photodetector PDIC for Blue-Violet Laser Diodes

CXA2674EM

CXA2673EM

The age of the blue-violet laser diode has arrived

CXA2674EM

making even higher recording densities possible.

RF/Servo PDIC for blue-violet laser diodes

Sony has now developed a new photodiode semi-

conductor wafer process and a new package for

photodetector IC for use with blue-violet laser

diodes.

Includes a high-sensitivity photodiode (0.3 A/W at 405 nm)

Low-noise amplifier

Standby mode function

Cavity mold glass sealed small package

This article introduces a chipset for use with blue-

violet laser diodes; a chipset that concentrates the

industry’s leading technologies in a unified system.

CXA2673EM

Laser front monitor PDIC for blue-violet laser diodes

Two-channel structure (Vin1, Vin2)

Standby mode function

Cavity mold glass sealed small package

operated. (Operating mode: 30 mA,

standby mode: 2 mA) This product is pro-

vided in a newly-developed package that

is appropriate for photodetection in the

wavelength range of the blue-violet laser.

CXA2674EM

Newly-Developed Package

for Blue-Violet Laser Diodes

The CXA2674EM is a photodetector IC

(PDIC) that detects both RF and servo

signals and mounted in a record/playback

optical pickup that supports the blue-vio-

let laser diode used for Blu-ray and other

optical discs. This device is fabricated in

a leading-edge process that improves the

optoelectronic conversion characteristics

in the blue-violet wavelength range to

almost the theoretical limits. It also

achieves a high signal-to-noise ratio by

including a low-noise amplifier. This

device features a standby mode function

that allows power consumption to be

minimized when the device is not being

Sony has developed a new cavity mold

glass sealed package for blue-violet laser

diodes. Conventional transparent plastic

packages have low transparency in the

wavelength range of the blue-violet laser

diode, and furthermore, it has been shown

that long-term exposure to blue-violet la-

ser diode light degrades plastic package

material. Therefore, Sony developed this

new package that mounts the silicon chips

in a molded cavity area and seals them in

that area with glass that has antireflection

coating on both sides, thus resolving both

these problems.

CXA2673EM

The CXA2673EM is a photodetector IC

(PDIC) developed for use as a laser power

monitor and mounted in a record/playback

optical pickup that uses the blue-violet

laser diode used for Blu-ray and other

optical discs. This device adopts the same

leading-edge process used for the

CXA2674EM and the same package. It

provides excellent performance as a front

monitor for blue-violet laser diodes.

No rose without a thorn.

While the blue laser diode was a

miraculous development, and it is

an extremely attractive device, it

was not easy to develop a PDIC

that could receive that light. Revis-

ing the fabrication process was, of

course, necessary, and we even

developed a new package in creat-

ing this new product! This is a very

friendly product and can be used

by almost anyone. It’s good to be

able to relax again now that this

project is done.
