Heidrun Schmitzer is a German-born experimental physicist and Professor of Physics in the Physics and Engineering Department at Xavier University in Cincinnati, Ohio. Her research is in optics and plasmonics, with particular emphasis on nonlinear optics, polarization optics and quantum optics.
Biography
Schmitzer earned her doctorate (Dr. rer. nat.) in optics and solid state physics at the University of Regensburg, Germany, under the supervision of Prof. Dr. Wolfgang Dultz. She subsequently worked on research projects in fiber and polarization optics for the German Telekom in Frankfurt, and taught for two years at the Montessori School in Regensburg. From 2000 to 2001 she was a postdoctoral research associate at the University of Chemnitz, holding a postdoctoral fellowship from the State of Saxony. She joined the physics faculty at Xavier University in 2002.
At Xavier she coordinates the department's study abroad program with the Ostbayerische Technische Hochschule (OTH) in Regensburg, which allows applied physics and engineering physics students to spend one or two semesters in Germany.
Work
Schmitzer's early research, carried out with Wolfgang Dultz and S. Klein, concerned the Pancharatnam–Berry geometric (topological) phase in polarization optics. This work included the demonstration of the nonlinearity of Pancharatnam's topological phase (Physical Review Letters, 1993), the tuning of an optical interference filter using the topological phase, and an experimental test of the path dependency of Pancharatnam's geometric phase (1998).
Her later work has covered nonlinear optical waveguides and second- and third-harmonic generation, optical trapping and the transfer of angular momentum from light to small birefringent particles, quantum optical interferometry with single photons and biphotons, plasmonic metal/dielectric multilayer waveguides, and the optical properties and lasing behavior of semiconductor nanowire photonic crystal arrays. She has also published physics education work, including undergraduate optical diffraction experiments reproducing Rosalind Franklin's X-ray photograph of DNA.
She holds a number of patents in optics, and has received the Women of Excellence Grant (2009, 2016), a technology grant for the development of a high-speed camera laboratory (2015), grants from the Research Corporation for the Advancement of Science (2005, 2008), and Xavier's Wheeler Award for curriculum development (2005).
