ABSTRACT

Continuous progress in optical communication technology and corresponding increasing data rates in core fiber communication systems are stimulated by the evergrowing capacity demand due to constantly emerging new bandwidth-hungry services like cloud computing, ultra-high-definition video streams. Nonlinear Fourier transform operations constitute nothing more than the core parts of the general inverse scattering transform method for the solution of initial-value problems associated with integrable evolutionary equations. Main direction in “eigenvalue communication” methodology can be categorized according to what part of the nonlinear spectrum is used for modulation and transmission. Skyrocketing demand for communication speed is exerting great pressure on the networks’ infrastructure at every scale, which explains the real motivation behind the overwhelming part of optical communications research.
