Ultracompact components for optical amplifiers
Coherent introduces product portfolio of optical amplifiers embedded in telecom transceivers and lidar subsystems.
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.
