Semidiscrete optical vortex droplets in quasi-phase-matched photonic crystals
Xiaoxi Xu, Feiyan Zhao, Jiayao Huang +6
A new scheme for producing semidiscrete self-trapped vortices (\textquotedblleft swirling photon droplets\textquotedblright ) in photonic crystals with competing quadratic ($χ^{(2)…

Vortex solitons in quasi-phase-matched photonic crystals
Feiyan Zhao, Xiaoxi Xu, Hexiang He +5
We report solutions for stable compound solitons in a three-dimensional quasi-phase-matched photonic crystal with the quadratic () nonlinearity. The photonic crystal is in…

Geometric phase with full-wedge and half-wedge rotation in nonlinear frequency conversion
Feiyan Zhao, Jiantao Lü, Hexiang He +3
When the quasi-phase matching (QPM) parameters of the nonlinear crystal rotate along a closed path, geometric phase will be generated in the signal and idler waves that p…
