Christian-Alexander Bunge received the Dipl.-Ing. degree in electrical engineering from university of technology Berlin (TU Berlin) in 1999. Until 2002, he was with TU Berlin's photonics group of Prof. Petermann, where he received his PhD. From 2002 to 2004, he was with the Polymer Optical Fiber Application Center (POF-AC) in Nuremberg, where he was responsible for fiber modeling and short-haul systems design. In 2004, he joined the TU Berlin as senior scientist, working on high- speed optical transmission systems, studying nonlinear optics, and modeling of optical components. In 2009, he became professor at Deutsche Telekom's university for telecommunication in Leipzig, where his main research interests are short-haul and access transmission techniques, multimode glass and polymer-fiber links, signal processing and optical sensors.
