Optical sorting of small chiral particles by tightly focused vector beamsThe identification and separation of substances by chirality has always been an important problem in biomedical research and industry. Light beams carry optical momentum, and can exert optical force on any object they impinge due to the transfer of momentum...Nov 27, 2019 -
Reconstruction of noisy images via stochastic resonance in nematic liquid crystalsHongjun Liu’s research team employed nematic liquid crystals as the nonlinear medium to recover noisy images via stochastic resonance, in which nonlinear coupling allows signals to grow at the expense of noise. The process is theoretically analyzed and the...Nov 27, 2019 -
Wenfu Zhang’s research team predicted that Multidimensional Manipulation of Photonic Spin Hall Effect with a Single‐Layer Dielectric MetasurfaceThe photonic spin Hall effect, originating from photonic spin-orbit interactions, has attracted considerable research interest due to its potential for applications in spin-controlled nanophotonics. However, most research efforts have focused only on 1D mod...Nov 27, 2019 -
Purely Kerr nonlinear model admitting flat-top solitonsJianhua Zeng’s research team elaborated one- and two-dimensional (1D and 2D) models of media with self-repulsive cubic nonlinearity, whose local strength is subject to spatial modulation that admits the existence of flat-top solitons of various types, incl...Nov 27, 2019 -
Effect of Ba(PO3)(2) addition on the optical properties of Tm3+-doped fluorophosphate glassesJiangbo She’s research team prepared Tm3+-doped fluorophosphate glasses with varying Ba(PO3)(2) content by the melt quenching technique and their thermal and optical properties were investigated by studying differential scanning calorimetry, Raman spectra,...Nov 27, 2019
