269-Type 14xx nm DFB Pump Laser Module
Description
The 269-type DFB pump laser module represents a
family of thermoelectrically cooled, high-power
lasers. These devices achieve stable wavelength
performance 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 DFB pump laser module is designed as a
continuous-wave (CW) optical pump source for erbium-doped
fiber amplifiers.

These new high-power DFB products represent a
breakthrough in 14xx nm pump laser technology by
integrating the beneficial characteristics of an exter-
nal FBG laser design (such as stimulated Brillouin
scattering suppression) with the superior relative-
intensity noise (RIN) performance of a DFB laser.
The combination of both characteristics is critical to
enable copropagating Raman pumping, which dis-
tributes gain over the first few kilometers of the trans-
mission fiber. The typical RIN value Agere Systems’
DFB lasers is –158 dB/Hz, a major improvement over
comparable external FBG-stabilized lasers with a
typical RIN of –125 dB/Hz. Integrating wavelength
stabilization into the chip improves the stabilization
over operating temperature and thereby eliminates
the need for an external FBG .
The laser modules incorporate a high-power, quan-
tum-well laser chip that achieves fiber powers up 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 DFB module is offered in a 14-pin, her-
metic butterfly package.
