Fiber-Optic Communication via the Nonlinear Fourier Transform

In future optical communication systems an ever increasing amount of data will have to be transmitted due to e.g. the increasing popularity of on-demand streaming of high-resolution audio and video formats or an increasing amount of machine-to-machine (M2M) communication. Since the achievable rates of state-of-the-art transmission systems seem to slowly saturate, it is necessary to think about alternative approaches concerning fiber optic data transmission. One promising tool seems to be the nonlinear Fourier transform (NFT), defining the nonlinear Fourier spectrum, which can be utilized for data transmission. Even though the corresponding pulse in time domain is influenced by fiber nonlinearity and dispersive effects during propagation, the nonlinear frequencies only exhibit a channel induced phase shift, that can be effectively compensated at the receiver.  In the context of my research, I try to optimize the utilization of NFT in optical systems, acquire knowledge about optimum transmission schemes for NFT and incorporate realistic system impairments into my observations.
