Cheng Zhang

Cheng Zhang is a UMD Postdoctoral Researcher in the Microsystems and Nanotechnology Division. He received a B.E. in Electrical Engineering from Shandong University, China in 2010, and a Ph.D. in Electrical Engineering from University of Michigan-Ann Arbor in 2016. Cheng received Optics and Photonics Education Scholarship from SPIE in 2010 and 2013, Michael Pate Optical Sciences Memorial Scholarship in 2014, Distinguished Leadership Award, Richard and Eleanor Towner Prize for Outstanding PhD Research, and Rackham Pre-doctoral Fellowship from University of Michigan, and Outstanding Overseas Student Award from the Chinese government in 2015.

He worked with Dr. L. Jay Guo for his doctoral research, where he focused on the development of ultra-thin and low-loss doped Silver films and their applications in various nano-photonic and electro-optical devices, including hyperbolic metamaterials, plasmonic waveguides, organic solar cells, and organic light emitting diodes. He also investigated several types of metamaterials for structural color generation, asymmetric light transmission, and polarization state control. He has expertise in nanoimprinting lithography for high-performance optical device fabrication. Cheng is currently working with Dr. Henri Lezec on numerically simulating, designing, fabricating, and experimentally characterizing advanced plasmonic devices and metamaterials operating at infrared, visible, and ultraviolet frequencies. Cheng also serves as the Event Leader of the OSA Nanophotonics Technical Group.
