Julie Sheridan Eng serves as Senior Vice President and General Manager of II-VI Incorporated’s Optoelectronic Devices and Modules Business Unit. In this role, she oversees 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. Prior to joining II-VI, Eng served as General Manager of Finisar Corporation’s 3D Sensing Business Unit, Executive Vice President of Finisar’s Transceiver Engineering, and Director of Transceiver Engineering at AT&T/Lucent/Agere.
During Eng’s 14-year tenure as head of Finisar’s Transceiver Engineering, under her engineering leadership, Finisar became a technology powerhouse in the fiber optics industry. The teams she managed delivered over 200 optoelectronics products to market, which were qualified by all major OEM and datacenter customers, shipped in very high volume, and contributed materially to the buildout of the fiber optic enterprise and datacenter networks. In addition, her team demonstrated many industry firsts, including the first demonstration of 100Gb/s (CFP) and 200Gb/s (QSFP56) transceivers, as well as the first demonstrations of 25Gb/s and 50Gb/s VCSELs and DMLs.
In 2018, Eng transitioned to 3D sensing VCSELs, and the teams she is managing have brought up state-of-the art 6² GaAs VCSEL laser manufacturing capability and have qualified multiple GaAs VCSEL 3D sensing products that are shipping in high volume into consumer and automotive markets for applications such as proximity sensing, facial recognition, and photo enhancement in mobile phones, as well as in-cabin sensing and LiDAR in automobiles.
Eng is a Past Chair of the IEEE Committee on Women in Engineering and presently serves on the SPIE Executive Advisory Group. She has published over a dozen papers, co-authored a book chapter, holds six U.S. patents, and has given numerous invited talks. Eng holds a B.A. degree summa cum laude in Physics from Bryn Mawr College, a B.S. degree with honors in Electrical Engineering from the California Institute of Technology (Caltech), and M.S. and Ph.D. degrees in Electrical Engineering from Stanford University. She was recently elected an Optica Fellow.
