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)…

Far-field three-dimensional deep-subwavelength focal spot with azimuthal polarization
Zhongquan Nie, Jiawei Liu, Xiaofei Liu +5
This work focuses on the generation of far-field super-resolved pure-azimuthal focal field based on the fast Fourier transform. A self-designed differential filter is first pioneer…
