Description
The 980-Type Pump Laser Module is a precision, high-performance, ultrahigh-reliability lightwave com- ponent that provides high output power light, in the 980 nm range. The 980-Type Pump Laser Module is comprised of a single-mode laser diode, PIN back- facet monitor, microlensed single-mode fiber, and a Fiber Bragg Grating (FBG) for improved stability, all encased in a specially designed 14-pin, oxygen free, butterfly package. The 980-Type Pump Laser Module is capable of providing a wide range of output power in the 974 nm to 984 nm wavelength range for erbium- doped amplifier (EDFA) system application. The pump laser module is designed and individually certi- fied for high-reliability operation and long-term life expectancy. The 980 nm InGaAs laser chip utilizes a ridge guide design for high performance and reliabil- ity. Chip and facet parameters are optimized for stabi- lized optical coupling and efficient pumping of the EDFA. The laser package design also includes a microlensed single-mode fiber and a planar InGaAs PIN back-facet photomonitor assembled in a modular organic-free hermetic package. Laser welding tech- nology is used for critical joints to achieve long-term stability. Data is archived for at least ten years. Each module is fully characterized and traceable. Long-life performance and reliability are ensured through extensive steps of burn-in, overstress, and power aging. The 980-T ype Pump Laser Module is available with a typical power output range of 20 mW to 70 mW.
