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. 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.

Absolute Maximum Ratings Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso- lute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect device reliability.Handling Precautions Electrostatic Discharge CAUTION: This device is susceptible to damage as a result of electrostatic discharge (ESD). Take proper precautions during both handling and testing. Follow guidelines such as EIA * Standard EIA 625. Agere Systems Inc. employs a human-body model (HBM) for ESD-susceptibility testing and protection-design eval- uation. ESD voltage thresholds are dependent on the critical parameters used to define the model. A standard HBM (resistance = 1.5 kΩ , capacitance = 100 pF) is widely used and, therefore, can be used for comparison pur- poses. The HBM ESD withstand voltage established for the 269-type laser pump module is ±500 V . * EIA is a registered trademark of The Electronic Industries Association.
