A soliton-like mode of generation of terahertz radiation by optical pulses with tilted wavefronts in a quadratic nonlinear medium has been studied. It has been shown that the formation of an optical-terahertz soliton at a positive dispersion of the group velocity above a critical value, which depends on the tilted angle, and at a negative nonlinear susceptibility in the optical range is accompanied by the generation of a terahertz unipolar soliton propagating in a different direction.

“…The eigenvalues of Zakharov-Shabat problem 4 are associated with soliton solutions of classical NLSE. 3 To obtain information about the soliton content of numerical solution of the NLSE with variable coefficients (1) the modified inverse scattering method 35 was used. Using numerical simulations we obtain eigenvalues as functions of their propagation distance: λ j = λ j (z).…”

It is known that eigenvalues of Zakharov-Shabat problem can be used to encode a signal in soliton communication lines. We propose to use dispersion oscillation fiber as a new versalite tool to control the eigenvalues. A fiber with sine-wave variation of the core diameter can be used to manage both real and imaginary parts of the eigenvalues. Change of real part of the eigenvalues results in a splitting of an optical breather into two distinct pulses propagating with the different group velocities. Change of imaginary parts of the eigenvalues allows to realize a reverse process of merge of two solitons into high-intensity pulse. The splitting of optical breather and merge of solitons can be obtained even under the strong effect of stimulated Raman scattering. We believe tools and techniques based on use of dispersion oscillating fiber will grant unprecedented control over soliton eigenstates.

An approach for the generation of high-intensity pulses via inelastic collision of solitons in dispersion variable fiber is proposed. The rogue-like pulse arises due to stimulated soliton collisions and non-adiabatic variation of the fiber dispersion. The analysis of the eigenvalues of Zakharov-Shabat spectral problem is given. We showed that the eigenvalues are affected by the fast change of the dispersion at the moment of soliton collision. High-intensity pulse generation under simultaneous effect of dispersion oscillation and stimulated Raman scatering is demonstarted. We proposed to use segmented fiber to generate the high-intensity pulse from inelastic soliton collision.
