Lumentum launches first uncooled 980nm DFB pump laser

Optical and photonic product maker Lumentum Holdings Inc of Milpitas, CA, USA has launched the T13 Series of 980nm pump laser modules, based on what is claimed to be an industry-first uncooled distributed feedback (DFB) 980nm pump laser chip. The T13 family of products combines a high-power DFB diode laser with additional components into an ultra-small form-factor coaxial package. Sample quantities are available now, with volume production in December.

"The T13 Series leverages the same TO-package demonstrated in numerous high-volume consumer applications and establishes the DFB's future role in compact, reliable 980nm pump lasers for optical amplification applications," says Jay Skidmore, VP R&D, High Power Lasers. "The DFB laser eliminates the external grating needed for conventional pump laser designs that opens a path towards much higher levels of integration," he adds. "Additional benefits include fiber length reduction, a decrease in the device's footprint, plus lower power requirements."

Operating up to 200mW, the T13 Series meets the telecoms industry's stringent requirements, including Telcordia GR-468-CORE for hermetic 980nm pump modules. The pump modules target single-channel and narrow-band amplifier applications for high-bit-rate transmission modules and CFPx transceivers.

"Introduction of the T13 Series pump is another example of Lumentum developing superior high-power laser technologies across our broad product portfolio to deliver best-in-class solutions," claims Doug Alteen, VP, product line management, Telecom. "The small pump laser package leverages the design and manufacturing of our high-volume 3D sensing lasers, which have proven to be highly reliable, with tens of millions of devices deployed."

Amongst Lumentum's portfolio of pump lasers for optical amplification, the 980nm Series of products supports erbium-doped fiber amplifiers operating at power levels of 100-900mW. The 14xx nm and 15xx nm Series products (deployed in Raman amplification) offer operating powers up to 600mW in wavelengths covering the C-band and L-band. The new uncooled T13 Series pumps are derived from a 980nm pump platform and significantly reduce power consumption and enable operation in extreme physical environments, says Lumentum.
