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…
Square-shaping of sturdy optical vortex droplets in quasi-phase-matched photonic crystals

This minireview provides a brief summary and a discussion of directions for further development of theoretical and, chiefly, experimental studies of bright solitons in optical coup…
Vortex clusters bifurcating from multipoles and second-order ring solitons
Hanqi Dong, Boris A. Malomed, Zhiwei Men
We address the existence, stability, and propagation dynamics of multipole solitons and vortex clusters in cubicquintic media subject to a harmonic trapping potential.We found that…
Abnormal motions of optical vortex-antivortex-coupled wavepackets in the parabolic potential
Haolin Lin, Junhui Jia, Chunhao Liang +4
The (quasi)particles or structured wavepackets in parabolic potential exhibit well-known harmonic oscillations, typically described by the Lissajous equations. However, such conven…

We systematically investigate semiclassical dynamics of the optical field produced by quantum nanoemitters (NEs) embedded in a periodic lattice of conducting nanorings (NRs), in wh…
