Request InfoCoherent Inc.Coherent Inc., Laser Group, has released optically pumped semiconductor laser technology that provides high-power laser output from a single-mode fiber. It can produce more than 500 mW of 980-nm output, in contrast to other 980-nm pump lasers that are limited to less than 200 mW. These lasers pump erbium-doped fiber amplifiers that boost optical signals in dense wavelength division multiplexing systems. The company says the new technology provides a simple and cost-effective means of preparing existing communications networks for the future.See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 9/18/2023CMOS VCSEL DriversThe Dove 800D and 410D PAM4 digital signal processors ICs from Credo were manufactured to address the increasing bandwidth requirements of hyperscale customers, AI backend clusters, and general...Photonics Spectra January 2024 IssueElectro-Optic ModulatorThe ROF10G Mach-Zehnder modulator from Beijing Rofea Optoelectronics is a LiNbO3 intensity modulator for high-speed optical communication, laser sensing, and radio over fiber (RoF) systems.
