Publikováno v: Phys. Rev. Lett. 130 157203 (2023)

We report solutions for stable compound solitons in a three-dimensional quasi-phase-matched photonic crystal with the quadratic ($\chi ^{(2)}$) nonlinearity. The photonic crystal is introduced with a checkerboard structure, which can be realized by m

Vortex gap solitons in spin-orbit-coupled Bose-Einstein condensates with competing nonlinearities

Autor: Xu, Xiaoxi, Zhao, Feiyan, Zhou, Yangui, Liu, Bin, Jiang, Xunda, Malomed, Boris A., Li, Yongyao

The formation and dynamics of full vortex gap solitons (FVGSs) is investigated in two-component Bose-Einstein condensates with spin-orbit coupling (SOC), Zeeman splitting (ZS), and competing cubic and quintic nonlinear terms, while the usual kinetic

Geometric phase with full-wedge and half-wedge rotation in nonlinear frequency conversion

Autor: Zhao, Feiyan, Lü, Jiantao, He, Hexiang, Zhou, Yangui, Fu, Shenhe, Li, Yongyao

Publikováno v: Opt. Exp. 29, 21820-21832 (2021)

When the quasi-phase matching (QPM) parameters of the $\chi^{(2)}$ nonlinear crystal rotate along a closed path, geometric phase will be generated in the signal and idler waves that participate in the nonlinear frequency conversion. In this paper, we
