Coherent Introduces Portfolio of Smaller Ultracompact Components for Optical Amplifiers Embedded in Telecom Transceivers and LiDAR Subsystems

PITTSBURGH, Feb. 15, 2023 (GLOBE NEWSWIRE) -- Coherent Corp. (Nasdaq: COHR), a global leader in optical communications and sensing technology, today announced the introduction of a portfolio of smaller ultracompact components that enable optical amplifiers embedded in next-generation high-speed telecom transceivers and in LiDAR subsystems.

Coherent, an early pioneer in embedded optical amplifiers, is introducing an entire family of smaller ultracompact components, including a micro-pump laser, a variable optical attenuator, and hybrid passive assemblies, all with a very low profile of less than 2.5 mm.

“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, 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 micro-pump laser is available with an output power of up to 400 mW.

Coherent will exhibit at OFC 2023 in San Diego, March 7-9, booth #3815, showcasing its new products and technology for next-generation optical communications networks and sensing.
