II-VI unveils 980nm pump module with on-board wavelength stabiliser

II‐VI, a provider of pump laser modules and micro-optics for optical amplifiers, has introduced new uncooled 980nm pump laser modules that feature patent-pending in-package wavelength stabilisation to enable optical amplification within small transceiver packages. These are increasingly required as high-bit-rate coherent transceivers continue to be designed into ever smaller packages to meet the needs of telecom carriers and cloud service providers for equipment with greater density requirements.

II-VI’s new 980nm uncooled pump laser module integrates a wavelength stabiliser into the small 8-pin mini-DIL package, eliminating the need for an external fibre Bragg grating in the pigtail assembly. Instead, II-VI’s new 980 nm uncooled pump laser features an 80µm low-bend-loss, small-bend-radius and polarisation-maintaining fibre pigtail.

Commenting on the product release, Dr. Sanjai Parthasarathi, vice president, product marketing and strategy, Optical Communications Group, said. “Our 8-pin uncooled mini-DIL pump lasers continue to be the smallest commercially available. With the integrated wavelength stabiliser technology, these pump lasers are now also the most versatile solutions for the growing market of optically amplified, high-bit-rate coherent transceivers.’

The new 980 nm pump lasers are built on II-VI’s field-proven OC-2 packaging platform with more than two million modules shipped to date. They also house II-VI’s market-proven G08 lasers to ensure superior wavelength-locking performance, reliability and stability. The new 980nm pump lasers, together with II-VI’s portfolio of ultra-compact hybrid passives based on II-VI’s micro-optics technology platform, enable low-noise and high-power optical amplification within transceiver form-factors previously unachievable, the company claims.

The modules are available now.
