Advanced Optical Communication Systems

Overall Course Objectives

To give the students insight into the most advanced and novel technologies, which will enable extreme data rates and heavily reduced energy consumption of optical communication systems. The students will get: a) insight into the fundamental challenges that optical communication systems face today (need for ever greater capacity, nonlinear transmission limits, energy consumption), and which technological solutions are being researched and developed today (spatial multiplexing, advanced optical and digital signal processing, integrated photonics), and b) numerical tools to simulate advanced nonlinear optical transmission effects and optical signal processing subsystems, such as optical time lenses, and to perform advanced digital signal processing.
