2024 Siegman International School on Lasers

Julie Eng

CTO, Coherent Corp.

Commercial Laser Applications

This talk will review multiple commercial examples of lasers:  compound semiconductor lasers for communications applications including artificial intelligence, and for sensing applications; optically pumped semiconductor lasers for semiconductor capital equipment, gene sequencing, and flow cytometry; excimer lasers for annealing; CW and high-speed fiber lasers for cutting, welding, muti-photon microscopy, and optogenetics.  Challenges in research and development, manufacturing, and the business of lasers will be discussed, along with a perspective on a career in industry. 

About the Speaker

Julie Sheridan Eng was named Chief Technology Officer (CTO) of Coherent in 2022.  Prior to becoming CTO, Dr. Eng served as Senior Vice President and General Manager of Coherent/II-VI’s Optoelectronic Devices and Modules Business Unit. In that role, she oversaw engineering, product management, and operations for GaAs vertical-cavity surface-emitting lasers (VCSELs), InP directly modulated lasers (DMLs) and detectors, and CMOS/BiCMOS integrated circuits for datacom and 3D sensing applications.  In this role, teams she managed ramped GaAs and InP devices for high volume consumer applications. 

Dr. Eng joined Coherent/II-VI in 2018 via the II-VI acquisition of Finisar.  She held various senior management positions at Finisar since joining the company in 2003, including Executive Vice President and General Manager of 3D Sensing, and Executive Vice President of Datacom Engineering.  Over the 15 years she managed Datacom and Transceiver Engineering, teams she managed released over 180 fiber optic transceiver products to manufacture and demonstrated numerous industry firsts.  Prior to joining Finisar, Dr. Eng was part of AT&T/Lucent/Agere, where she managed datacom transceivers. 

Dr. Eng is a Past Chair of the IEEE Committee on Women in Engineering and presently serves on the Board of Directors of Optica (formerly the Optical Society of America). She has published over a dozen papers, co-authored a book chapter, holds six U.S. patents, and has given numerous invited talks. She holds a B.A. degree summa cum laude in Physics from Bryn Mawr College and a B.S. degree in Electrical Engineering with honors from the California Institute of Technology (Caltech).  She earned M.S. and Ph.D. degrees in Electrical Engineering from Stanford University.  In 2022, she was elected Fellow of Optica for distinguished contributions to the advancement of optics and photonics.
