Stable high-charge vortex dissipative solitons in azimuthally modulated waveguide arrays with localized gain
Changming Huang, Qidong Fu, Li Ma
We study the existence and dynamical properties of vortex solitons in Kerr media supported by azimuthally modulated waveguide lattices with localized gain and nonlinear loss. In th…

Topological linear and nonlinear gap modes in defected dimer lattice with fourth-order diffraction
Xiaoyang Wang, Qidong Fu, Changming Huang
In this study, we investigate the optical properties of linear and nonlinear topological in-phase, out-of-phase, and edge modes in a defected dimer lattice with fourth-order diffra…
