Ping Zhao

Research Specialist at Photonics

Ping Zhao received the B.Sc. and Ph.D. degrees from Huazhong University of Science and Technology (HUST), Wuhan, China, in 2009 and 2014, respectively. His research topic during the PhD period was micro-nano optical waveguide devices and their applications. After his graduation from HUST, he worked at Huawei Technology as a senior research engineer on high-speed optical communications for five years. Later, he joined Chalmers in 2019 starting from postdoc and now is a staff researcher with the Photonics Laboratory in the Department of Microtechnology and Nanoscience. His research topics now address more on integrated nonlinear photonic waveguides/devices, low-noise parametric amplifier and their applications in optical communications. To date, he has authored/co-authored 26 peer-reviewed papers (20 as first author) and 10 granted patents (7 as main inventors), receiving Excellent Doctoral Thesis Prize of Hubei Province in 2015. Especially, the chip-based optical parametric amplification with the lead contribution from Dr Zhao was picked by “Optics in 2022” of Optica (formerly OSA). He is a guest editor of Photonics and Micromachines, holding the membership of the IEEE and Optica.
