Abstract

We study the properties of second order solitons with two nonlinear Fourier transform eigenvalues that are very close to each other. We have found that these solitons can be approximated with a linear combination of two fundamental solitons. The error in the approximation reduces as the gap between the eigenvalues reduces. This relation can be used to explain the correlation existing between eigenvalues, nonlinear spectral amplitudes and spectral phases and to encode information more efficiently on more packed second order soliton signals.
