Vector solitons in nonlinear lattices with competing SPM and XPM terms
Liangwei Zeng, Boris A. Malomed, Dumitru Mihalache +1
We demonstrate that two-component photonic nonlinear lattices with opposite signs of the out-of-phase spatially modulated SPM and XPM coefficients can support two types of optical…
Flat-top solitons and anomalous interactions in media with even-order dispersions and competing nonlinearities
Xueqing He, Shijie Hao, Lijing Xing +3
Flat-top (FT) solitons are optical pulses that arise from the balance of dispersion and self-phase modulation in media with the competing cubic-quintic nonlinearity. Previously, FT…
Solitons in composite linear-nonlinear moiré lattices
Liangwei Zeng, Boris A. Malomed, Dumitru Mihalache +2
We produce families of two-dimensional gap solitons (GSs) maintained by moiré lattices (MLs) composed of linear and nonlinear sublattices, with the defocusing sign of the nonlinear…
