4 x 800 mW Fiber Bragg Grating Stabilized 980 nm Pump Modules

The Lumentum D4 Series is quad-chip 980 nm pump laser module with each emitter independently controlled. It uses a number of revolutionary design steps to provide high optical power density within a compact space. The D4 series pump module incorporates the Lumentum high-reliability, high-efficiency 980 nm laser diode in a cooled fiber Bragg grating-stabilized 14-pin low profile butterfly design. The module meets the stringent requirements of the telecommunications industry, including Telcordia GR-468-CORE for hermetic 980nm pump modules.

The D4 Series pump module, which uses fiber Bragg grating stabilization to lock the emission wavelength, provides a noise- free, narrowband spectrum, even under changes in temperature, drive current and optical feedback. Wavelength selection is available for applications requiring the highest performance in spectrum control with the highest power available.
