Maciej Dems, D.Sc.

assistant professor
Photonics Group

Maciej Dems received his M.Sc. and Ph.D. degrees in physics from Lodz University of Technology, Poland, in 2002 and 2007, respectively, and a habilitation degree in physics from Warsaw University in 2018. From 2011 to 2014 he was leading an R+D project—within the framework an R+D project within the framework LIDER funded by the Polish National Centre for Research and Development—which main goal was the development of an advanced software for modeling of various photonic structures on a sub-wavelength scale. Currently, his research interest is a broad range of sub-wavelenght photonic devices: photonic crystals, high-contrast gratings, DFB lasers and micro-structured VCSELs.
