Role of internal and continuum modes in modulational instability of quadratic solitons.
نویسنده
چکیده
The role of internal and continuum modes in the modulational instability of spatial quadratic solitons is examined by asymptotic and numerical analyses. It is shown that these modes generate novel spatially symmetric and asymmetric modulation instability branches, which underline soliton dynamics throughout a wide region of the wave-vector mismatch.

Modulational instability and solitons in a periodic dissipative feedback system
We review our recent experimental results on control of the modulational instability, pattern formation, and solitons in a nonlinear discrete dissipative feedback system. We show that the discreetness and bandgap effects can provide efficient control of the nonlinear instability modes of the system. Furthermore, we explore the possibilities for excitation of dissipative discrete solitons in suc...
متن کاملMobility of Discrete Solitons in Quadratic Nonlinear Media
We study the mobility of solitons in lattices with χ (2) (second-harmonic-generating) nonlinearity. Contrary to what is known for their χ (3) counterparts, we demonstrate that discrete quadratic solitons can be mobile not only in the one-dimensional (1D) setting, but also in two dimensions (2D), in any direction. We identify parametric regions where an initial kick applied to a soliton leads to...
متن کاملSpatial optical solitons governed by quadratic nonlinearity.
We demonstrate that a dielectric medium with purely quadratic nonlinearity [the so-called chi((2)) material] can display self-focusing phenomena through a new type of modulational instability of the interacting fundamental and second-harmonic field components and therefore can support propagation of (two-wave) optical solitons. We prove the existence of a family of such solitons, which are foun...
متن کاملStabilization of dark and vortex parametric spatial solitons.
We demonstrate that a weak defocusing Kerr effect in an optical medium with predominantly quadratic [or chi((2))] nonlinear response can eliminate the parametric modulational instability of plane waves, leading to the existence of stable two-wave dark and vortex spatial solitons.
متن کاملInstabilities of cavity solitons in optical parametric oscillators.
Using an example of cavity solitons in optical parametric oscillators it is demonstrated that Hopf instability of these dissipative structures can be directly associated with internal modes of their conservative counterparts. The latter ones are free propagating quadratic solitons in this case. Linear stability analysis and numerical simulation also reveal multistability and complex instability...
