Coherent Corp. (Nasdaq: COHR; formerly II-VI after the acquisition of Coherent Inc.) has named Dr. Julie Sheridan Eng chief technology officer (CTO). She previously served as senior vice president and general manager of Optoelectronic Devices and Modules Business Unit.

Eng joined the company with II-VI’s acquisition of Finisar in 2019, where she had worked since 2003. During her tenure at Finisar, Eng held such titles as executive vice president and general manager of 3D sensing and executive vice president of datacom engineering. Subsequent to the Finisar acquisition, she oversaw engineering, product management, and operations for GaAs VCSELs, InP directly modulated lasers and detectors, and CMOS/BiCMOS integrated circuits for datacom, 3D sensing, and high-volume consumer applications as head of the II-VI Optoelectronic Devices and Modules Business Unit.

Eng began her career at AT&T Bell Laboratories, where she led the development of optical datacom transceivers.

“The appointment of Julie Eng as Chief Technology Officer not only recognizes her sustained contributions to the development of an entire industry, but also reveals an important step in the evolution of our exciting growth plans,” said Dr. Vincent D. Mattera, Jr., Coherent’s chair and CEO. “Dr. Eng will focus on Coherent’s future technology platforms that will enable us to address the long-term and irreversible market trends that are core to our strategy and to our drive for sustainably profitable growth. Consistent with our vision of a world transformed through innovations vital to a better life today and the sustainability of future generations, she will focus on the opportunity for us to extend our technology platforms across the company including the creation of new materials for energy generation, transmission, and storage, basic research around next-generation quantum technologies, breakthroughs required for the sixth generation of wireless networks, and the adoption of digital technologies, machine learning, and artificial intelligence across our operations and in our products and services.”

Dr. Christopher Koeppen, CTO of II-VI at the time of its acquisition of Coherent, is now chief innovation officer of the combined company.
