Maciej Dems

assistant professor
Photonics Group

Maciej Dems received his M.Sc. degree in physics from Lodz University of Technology, Poland, in 2002 on the subject of strain determination in thin-layered structures. His current interests are photonic band gap materials (also known as photonic crystals) and their application to the new generations light-emitting instruments. In 2007 he defended Ph.D. dissertation in this subjet. Furthermore, Maciej Dems works on development of numerical methods for modeling of various photonic structures of a sub-wavelength scale. Since 2011 he leads an R+D project within the framework LIDER funded by the Polish National Centre for Research and Development. For many years he is a regular member of the Optical Society of America and the Society of Photo-Optical Instrumentation Engineers (SPIE).
