The Lumentum D22 Series is dual-chip 980 nm pump laser module with each emitter independently controlled. It is based on a number of revolutionary design steps and provides high optical power density within a compact space. The D22 series pump module incorporates the high-reliability, high-efficiency Lumentum 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 980 nm pump modules

The D22 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.
