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…

Observation of nonlinear higher-order topological insulators with unconventional boundary truncations
Changming Huang, Alexander V. Kireev, Yuxin Jiang +10
In higher-order topological insulators (HOTIs), topologically nontrivial phases are usually associated with the shift of Wannier centers to topologically nontrivial positions on 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…
