The high-power JDSU laser chip is hermetically sealed in a low-profile, epoxy- and flux-free, 14-pin butterfly package and fitted with a thermistor, thermoelectric cooler, and monitor diode. The module meets the stringent requirements of the telecommunications industry, including Telcordia™ GR-468-CORE for hermetic 980 nm pump modules. The 2900-FL Series pump module uses fiber Bragg grating stabilization to “lock” the emission wavelength. It provides a noise-free narrowband spectrum, even under changes in temperature, drive current, and optical feedback. Wavelength selection is available for applications that require the highest performance in spectrum control with the highest available powers. The 2900-FL Series design also offers tight tracking of fiber-coupled power via the monitor diode signal.

The maximum operating power (Pop) will be achieved at a device-specific maximum operating current (Iop). The individual value of Iop is noted on the hardcopy data sheet shipped with the device. All values of Iop are limited by the maximum value listed in Table 2. 2. The module is kink-free up to a minimum kink-free power (Pmax) that the module will achieve at a device-specific kink-free current (Imax). The individual value of Imax is noted on the hardcopy data sheet shipped with the device. All values of Imax are limited by the maximum value listed in Table 2. 3. The pump laser shall never be operated at a power higher than the Pop throughout its lifetime. At beginning of life (BOL), the operating current shall never be higher than the device-specific Iop that is noted on the hardcopy data sheet shipped with the device. At end of life (EOL), the operating current shall never be higher than the device-specific Imax that is noted on the hardcopy data sheet shipped with the device. 2900-FL SERIES 4 Table 3: Available Peak Wavelength Selection (Tamb = 25±3 °C, 50 mW < P < Pop) Product Code Minimum Peak Wavelength Maximum Peak Wavelength 29-7402-xxx-FL 29-7552-xxx-FL 29-7602-xxx-FL 29-7702-xxx-FL 973.5 nm 974.5 nm 975.0 nm 976.0 nm 975.0 nm 976.5 nm 977.0 nm 978.0 nm Table 4: Electro-Optical Performance (BOL,Tcase = 0 to 75 °C,TLD = 25 °C, -50 dB reflection, unless noted otherwise) Parameter Symbol Test Condition Minimum Maximum Threshold current Forward voltage Spectral width Peak wavelength tuning Side-mode suppression ratio Relative optical power stability Ith Vf ΔλRMS ΔλP/ΔΤamb SMSR If = Iop 50 mW < P < Pop 50 mW < P < Pop 50 mW < P < Pop Peak-to-peak, T = 10 min, 50 kHz sampling, Tcase = 25 °C 20 mW < P < Pop 12 mW < P < 20 mW 3.5 mW < P < 12 mW 20 mW < P < Pop1 20 mW < P < Pop2 20 mW < P < Pop Tcase = 75 °C Tcase = 75 °C Tcase = 75 °C, BOL Tcase = 75 °C, EOL 15 dB 30 mA 2.5 V 2.0 nm 0.02 nm/°C - -8% 0.90 2 µA/mW 9.5 kΩ 3600 K - 4% 10% 25% 8% 1.10 10 µA/mW 1.9 A 2.5 V 10.5 kΩ 4200 K 8.2 W 9.5 W Tracking error Tracking ratio Monitor diode responsivity TEC current TEC voltage Thermistor resistance Thermistor constant Module power consumption TE TR RespBF ITEC VTEC Rth B 1. The tracking error is defined as the normalized change of output power relative to the operating power over case temperature range (0 °C to 75 °C), at constant back-face monitor current corresponding to the operating power at 25 °C. 2. The tracking ratio is a measure of the front-to-back tracking when the output power is varied. On a plot of optical power versus back-face photocurrent, a straight line is drawn between the minimum power (20 mW) and the operating power (Pop) points. The tracking ratio is defined as the ratio between measured optical power (shown as data points on the plot) to the value derived from the straight line. 2900-FL SERIES 5 Ordering Information For more information on this or other products and their availability, please contact your local JDSU account manager or JDSU directly at 1-800-498-JDSU (5378) in North America and +800-5378-JDSU worldwide or via e-mail at [email protected].

Avoid looking directly into the fiber when the device is in operation. CAUTION: THE USE OF OPTICAL INSTRUMENTS WITH THIS PRODUCT INCREASES EYE HAZARD. Operating the laser diode outside of its maximum ratings may cause device failure or a safety hazard. Power supplies used with this component cannot exceed maximum peak optical power. CW laser diodes may be damaged by excessive drive current or switching transients. When using power supplies, the laser diode should be connected with the main power on and the output voltage at zero. The current should be increased slowly while monitoring the laser diode output power and the drive current. Careful attention to heatsinking and proper mounting of this device is required to ensure specified performance over its operating life. To maximize thermal transfer to the heatsink, the heatsink mounting surface must be flat to within .001” and the mounting screws must be torqued down to 1.5 in.-lb. ESD PROTECTION—Electrostatic discharge (ESD) is the primary cause of unexpected laser diode failure. Take extreme precaution to prevent ESD. Use wrist straps, grounded work surfaces, and rigorous antistatic techniques when handling laser diodes. 2900-FL SERIES Labeling Because of the small size of these devices, the output power and laser emission indicator label shown below is attached to the individual shipping container.
