The company headquartered in Pennsylvania, an early pioneer in embedded optical amplifiers, is introducing an entire family of smaller ultracompact components, including a micropump laser, a variable optical attenuator, and hybrid passive assemblies, all with a very low profile of less than 2.5 millimeters.

“We have achieved a level of miniaturization that is unmatched in the industry with a complete set of components that enable optical amplifiers to be easily embedded in small modules such as pluggable high-speed transceivers, in the very small QSFP-DD form factor, and miniature automotive lidar systems,” said Dr Sanjai Parthasarathi, Coherent’s chief marketing officer. “Leveraging highly automated assembly, these components will scale cost-competitively with the rapidly growing demand.”

The components are available individually and as custom assemblies, including with erbium- and erbium/ytterbium-doped fiber from Coherent. They come in standard or extended temperature ranges, and with bend-insensitive fiber input and output on a single side. The micropump laser is available with an output power of up to 400 milliwatts.

Coherent will exhibit at OFC 2023 in San Diego, March 7 – 9, showcasing its new products and technology for next-generation optical communications networks and sensing.
