Data Sheet 980nm Pump Laser Module Grating Stabilized, 300mW LC94 These lasers are designed as pump sources for Erbium-Doped Fiber Amplifier (EDFA) applications. Processes and techniques of coupling the fiber to the laser allow high output powers that are very stable with both time and temperature. The grating is located in the pigtail to stabilize the wavelength. Devices are available with kink free output powers to 300mW. The LC94 series pump module utilises a double Fiber Bragg Grating design for enhanced wavelength and power stability performance. This product has been designed to ensure superior wavelength locking over drive current, temperature and optical feedback changes. Features: • Double Fiber Bragg Grating wavelength stabilization • High output power, up to 300mW kink free • Single-mode fiber pigtail • Internal thermoelectric heatpump and monitor photodiode • Hermetically sealed 14-pin butterfly package • Telcordia GR-468-CORE compliant • Field proven high reliability • RoHS compliant Applications: • Low noise EDFAs • Dense wavelength division multiplexing (DWDM) EDFAs • CATV Applications 1 Data Sheet Characteristics Conditions unless otherwise stated: Case temperature -20 to +75°C Submount temperature 25°C Monitor diode bias -5V CW operation Kink-free fiber-coupled output power: (Wavelength = 974nm) LC94ZC74-20R LC94ZD74-20R LC94ZE74-20R LC94ZF74-20R LC94ZG74-20R LC94ZH74-20R LC94ZJ74-20R LC94ZK74-20R LC94ZL74-20R LC94ZM74-20R Parameter 100mW 110mW 120mW 130mW 140mW 150mW 160mW 170mW 180mW 190mW LC94A74-20R LC94B74-20R LC94C74-20R LC94D74-20R LC94E74-20R LC94F74-20R LC94G74-20R LC94H74-20R LC94J74-20R LC94K74-20R LC94L74-20R Min Threshold current (Ith) Operating drive current (If) Typ Max Unit 30 40 mA 250 300 350 400 450 500 550 600 mA mA mA mA mA mA mA mA 2.5 V ZC thru ZD ZE thru ZF ZG thru ZJ ZK thru ZM A thru B C thru E F thru K L Forward voltage (Vf) 1.9 Centre wavelength (λc) 974 Spectral width (RMS @ -13dB) 0.2 nm 1 nm Spectrum stability (t = 60s) ±0.5 nm Temperature dependence of peak wavelength 0.02 nm/°C Wavelength tolerance ±0.5 nm 25 µA/mW 50 nA Monitor detector responsivity 1.0 8 Monitor dark current Thermistor resistance (at 25°C) 9.5 10 10.5 kΩ Intended laser submount operating temperature 20 25 30 °C 0.05 0.1 dB dB 26.5 °C Heatpump current (∆T = 50°C, If = 500mA) 1.3 A Heatpump voltage (∆T = 50°C, If = 500mA) 2.8 V Power stability Peak-to peak, t = 60s, DC to 50kHz sampling, TC = 25°C >20mW 10-20mW Laser temperature, R = 10kΩ 2 200mW 210mW 220mW 230mW 240mW 250mW 260mW 270mW 280mW 290mW 300mW 23.5 Data Sheet Absolute Maximum Ratings Parameter Min Max Unit Operating temperature -20 75 °C Storage temperature -40 85 °C Laser forward current 800 mA Laser reverse voltage 2 V Heatpump current 1.8 A Lead soldering temperature (10s max) 260 °C Fibre bend radius 30 Package Outline Drawing and Dimensions 3 Fiber Specification Puremode HI980 or equivalent 250µm primary coated. mm Data Sheet Connections 4 Pin # Description Pin # Description 1 Peltier cooler (+) 8 Not connected 2 Thermistor 9 Not connected 3 Monitor anode (-) 10 Laser anode (+) 4 Monitor cathode (+) 11 Laser cathode (-) 5 Thermistor 12 Not connected 6 Not connected 13 Case ground 7 Not connected 14 Peltier cooler (-) 7 6 5 4 3 2 1 8 9 10 11 12 13 14 Data Sheet RoHS Compliance Bookham is fully committed to environment protection and sustainable development and has set in place a comprehensive program for removing polluting and hazardous substances from all of its products.
