The Chair of Communications deals with various research topics in the field of optical communications. Focus areas currently are data transmission within and between data centers as well as long-distance transmission systems. For data center networks the challenge lies in using cost efficient components for very high data rates (e.g. 800 Gb/s Ethernet). To achieve this goal digital signal processing algorithms are combined with machine learning approaches. For long-haul networks the nonlinear degradation along the transmission line is significant. Very long distances can be bridged almost without distortions using modern signal processing schemes (e.g. the nonlinear Fourier transform). To reduce the numerical complexity especially photonic signal processing schemes are followed (e.g. optical reservoir computing). In all of the above areas student assistants can be involved. The working fields reach from (MATLAB-based) simulations to assisting in optical transmission experiments. All jobs are in close collaboration with the PhD students.
