Mohamed Atef received the B.Sc. and M.Sc. degrees in Electrical Engineering, Electronics and Communications from Assiut University, Egypt, in 2000 and 2005 respectively. From 2006 to 2007 he was in Czech Technical University in Prague, Department of Microelectronics, working on the improvement of optical properties of quantum dots. He received the Ph.D. from Vienna University of Technology, Institute of Electrodynamics, Microwave and Circuit Engineering in 2010 then served as a post-doctoral researcher up to 2012. Since 2010 he is an assistant professor at Electrical Engineering Dept., Assiut University, Egypt. His current research interests are in the area of optoelectronic integrated circuit and communications over plastic optical fiber. He is author of the Springer book ‘Optical Communication over Plastic Optical Fibers: Integrated Optical Receiver Technology’. Furthermore, he is author and co -author of around 35 scientific publications. Since 2012 he is senior member IEEE. />Dr. Horst Zimmermann, received the diploma in Physics in 1984 from the University of Bayreuth, Germany, and the Dr.-Ing. degree in the Fraunhofer Institute for Integrated Circuits (IIS-B), Erlangen, Germany in 1991. Then, Dr. Zimmermann was an Alexander-von-Humboldt Research-Fellow at Duke University, Durham, N.C., working on diffusion in Si, GaAs, and InP until 1992. In 1993, he joined the Chair for Semiconductor Electronics at Kiel University, Kiel, Germany, where he lectured optoelectronics and worked on optoelectronic integration. Since 2000 he is full professor for Electronic Circuit Engineering at Vienna University of Technology, Vienna, Austria. His main interests are in design and characterization of analog and nanometer CMOS circuits as well as optoelectronic integrated CMOS and BiCMOS circuits. He is author of the Springer books 'Integrated Silicon Optoelectronics' and 'Silicon Optoelectronic Integrated Circuits' as well as coauthor of “Highly Sensitive Optical Receivers”and “Optical Communication over Plastic Optical Fibers”. In addition he is author and co-author of more than 400 publications. In 2002 he became Senior Member IEEE.
