269-Type 14xx nm Pump Laser Module

with Fiber Grating

Applications

■ Raman pump modules (RPM)

■ Erbium-doped fiber amplifiers (EDFA)

Description

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.

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

■ High-coupled rated output power up to 280 mW,

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.

■ Available with fiber grating for wavelength stability

(1420 nm—1510 nm)

■ Wide environmental range

The laser modules incorporate a high-power, quan-

tum-well laser chip that achieves grating-stabilized

fiber powers ranging to 280 mW.

■ Field-proven packaging technology

■ InGaAsP/InP high-power, strained multiple quan-

tum-well (MQW) chip design

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.

■ Internal thermoelectric cooler (TEC)

■ InGaAs PIN photodetector back-facet monitor

■ Single-mode and polarization-maintaining fiber pig-

tails

■ Compact, 14-pin butterfly package

■ Industry compatible package and pinout

The 269-type module is offered in a 14-pin, hermetic

butterfly package.
