269-Type 14xx nm Pump Laser Module
with Fiber Grating
Applications
s Raman pump modules (RPM)
s Erbium-doped fiber amplifiers (EDFA)
Description
Offering superior wavelength stability, the 269-type pump
laser module with fiber grating is designed as a continuous-
wave (CW) optical pump source for erbium-doped fiber ampli-
fiers and Raman pump modules.
Features
s High-coupled rated output power up to 280 mW,
CW
s Available with fiber grating for wavelength stability
(1420 nm—1510 nm)
s Wide environmental range
s Field-proven packaging technology
s InGaAsP/InP high-power, strained multiple quan-
tum-well (MQW) chip design
s Internal thermoelectric cooler (TEC)
s InGaAs PIN photodetector back-facet monitor
s Single-mode and polarization-maintaining fiber pig-
tails
s Compact, 14-pin butterfly package
s Industry compatible package and pinout
The 269-type pump laser module with fiber grating
represents a family of thermoelectrically cooled,
high-power lasers. These modules utilize a fiber
Bragg grating to achieve stable wavelength perfor-
mance within the 1420 nm to 1510 nm range, over
the full operating temperature range. They are
designed as continuous-wave (CW) optical pump
sources for dense wavelength-division multiplexing
(DWDM) EDFA and Raman applications operating in
the C- and L-bands. The 269-type laser modules with
polarization-maintaining fiber are particularly suitable
for use in RPM designs requiring the high-power
combinations of multiple pumps.
The laser optical spectrum is locked by the fiber grat-
ing over a wide optical power range. The optical
spectrum is very narrow and the peak wavelength is
nearly insensitive to temperature variations and back
reflections.
The laser modules incorporate a high-power, quan-
tum-well laser chip that achieves grating-stabilized
fiber powers ranging to 280 mW.
An integral thermoelectric cooler (TEC) stabilizes the
laser at room temperature and, combined with a her-
metic environment, allows the device to achieve
high-power operation over the extended temperature
range of 0 °C to 75 °C. An internal InGaAs PIN pho-
todiode, mounted behind the laser diode, functions
as the laser detector and monitors light emissions
from the rear facet of the laser.
The 269-type module is offered in a 14-pin, hermetic
butterfly package.

Mounting and Connections
CAUTION: This device is susceptible to damage as
a result of electrostatic discharge.
Proper precautions should be taken
during both handling and testing.
The base of the laser module (see Outline Diagram)
should be maintained at or below 75 °C (maximum)
during operation. Interfaces between the laser module
base and heat sink must be clean, and the use of a
thermal filler may be necessary.
Mounting Instructions
The minimum fiber bend radius is 1.0 in.
To avoid degradation in performance, mount the mod-
ule on the board as follows:
1. Place the bottom flange of the module on a flat heat
sink at least 0.5 in. x 1.180 in. (12.7 mm x 30 mm)
in size. The surface finish of the heat sink should be
better than 32 µin. (0.8 µm), and the surface flat-
ness must be better than 0.001 in. (25.4 µm). Using
thermal conductive grease is optional; however,
thermal performance may be improved if conductive
grease is applied between the bottom flange and
the heat sink.
2. Mount four #2-56 screws with Fillister heads
(M2-3 mm) at the four screw hole locations (see
Outline Diagram). The Fillister head diameter must
not exceed 0.140 in. (3.55 mm). Do not apply more
than 1 in./lb. of torque to the screws.
