Making the PT symmetry unbreakable
Vitaly Lutsky, Eitam Luz, Er'el Granot +1
It is well known that typical PT-symmetric systems suffer symmetry breaking when the strength of the gain-loss terms exceeds a certain critical value. We present a summary of recen…
Multi-soliton states under triangular spatial modulation of the quadratic nonlinearity
Vitaly Lutsky, Boris A. Malomed
We introduce multi-soliton sets in the two-dimensional medium with the second-harmonic-generating nonlinearity subject to spatial modulation in the form of a triangle of singular p…
Solitons supported by singular modulation of the cubic nonlinearity
Vitaly Lutsky, Boris A. Malomed
A model of the optical media with a spatially structured Kerr nonlinearity is introduced. The nonlinearity strength is modulated by a set of singular peaks on top of a self-focusin…
One- and two-dimensional solitons supported by singular modulation of quadratic nonlinearity
Vitaly Lutsky, Boris A. Malomed
We introduce a model of one- and two-dimensional (1D and 2D) optical media with the nonlinearity whose local strength is subject to cusp-shaped spatial modulation, $χ^{(2…
Optical-parametric-oscillator solitons driven by the third harmonic
Vitaly Lutsky, Boris A. Malomed
We introduce a model of a lossy second-harmonic-generating (chi^2) cavity externally pumped at the third harmonic, which gives rise to driving terms of a new type, corresponding to…
