Dynamical switching of lasing emission by exceptional point modulation in coupled microcavities
Yicong Zhang, Weiwei Liu, Qingjie Liu +2
In a non-Hermitian optical system with loss and gain, an exceptional point (EP) will arise under specific parameters where the eigenvalues and eigenstates exhibit simultaneous coal…
Epoxy-inspired Nonlinear Interface Integrating Monolayer Transition-Metal Dichalcogenides with Linear Plasmonic Nanosieves
Xuanmiao Hong, Guangwei Hu, Wenchao Zhao +11
Although TMDC monolayers offer giant optical nonlinearity within few-angstrom thickness, it is still elusive to modulate and engineer the wavefront of nonlinear emissions. The grai…
Tungsten disulfide-gold nanohole hybrid metasurfaces for nonlinear metalens in the visible region
Jiawei Chen, Kai Wang, Hua Long +5
Recently, nonlinear hybrid metasurface comes into an attractive new concept in the research of nanophotonics and nanotechnology. It is composed of semiconductors with an intrinsica…
Precise Determination of the Crystallographic Orientations in Single ZnS Nanowires by Second-Harmonic Generation Microscopy
Hu Hongbo, Wang Kai, Long Hua +3
We report on the systematical study of the second-harmonic generation (SHG) in single zinc sulfide nanowires (ZnS NWs). The high quality ZnS NWs with round cross-section were fabri…
Laterally emitted surface second harmonic generation in a single ZnTe nanowire
Weiwei Liu, Kai Wang, Zhe Liu +2
We report a direct observation on the unique laterally emitted surface second harmonic generation (SHG) in a single ZnTe nanowire. The highly directional surface SHG signal that po…
