Peter J. Winzer received his Ph.D. from the Vienna University of Technology, where he worked on space-borne lidar and laser communications for the European Space Agency. At Bell Labs since 2000, he has focused on many aspects of fiber-optic communications, including advanced optical modulation, multiplexing, and detection. He has contributed to several high-speed optical transmission records from 100 Gb/s to 1 Tb/s and has been widely promoting spatial multiplexing to overcome the optical networks capacity crunch. He has amply published and patented and is actively involved with the IEEE Photonics Society and the Optical Society (OSA), including service as Program Chair of ECOC 2009, Program/General Chair of OFC 2015/17, and the current Editor-in-Chief of the IEEE/OSA Journal of Lightwave Technology. Dr. Winzer is a Highly Cited Researcher, a Bell Labs Fellow, a Fellow of the IEEE and the OSA, and an elected Member of the US National Academy of Engineering. He received the 2018 John Tyndall Award.
