980-Type Ultrahigh-

Reliability Pump Laser Module

Applications

■ Undersea optical transmission systems

■ Ultrahigh reliability optical communications for mili-

tary systems

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-Type Pump Laser Module is available

with a typical power output range of 20 mW to

70 mW.

The 980-Type Ultrahigh-Reliability Pump Laser Module is ide-

ally suited for fiber amplifier-based optical transmission sys-

tems that require a long-term life expectancy.
