Journal ArticleDOI
Ultrafast control of vortex microlasers.
Can Huang,Chen Zhang,Shumin Xiao,Yuhan Wang,Yubin Fan,Yilin Liu,Nan Zhang,Geyang Qu,Hongjun Ji,Jiecai Han,Li Ge,Li Ge,Yuri S. Kivshar,Qinghai Song,Qinghai Song +14 more
TL;DR: The results provide an approach that breaks the long-standing trade-off between low energy consumption and high-speed nanophotonics, introducing vortex microlasers that are switchable at terahertz frequencies.
Journal ArticleDOI
All-Dielectric Full-Color Printing with TiO2 Metasurfaces
Shang Sun,Zhenxing Zhou,Zhenxing Zhou,Chen Zhang,Chen Zhang,Yisheng Gao,Yisheng Gao,Zonghui Duan,Zonghui Duan,Shumin Xiao,Shumin Xiao,Qinghai Song,Qinghai Song +12 more
TL;DR: The detailed numerical analysis shows that the distinct colors were generated by the electric resonance and magnetic resonances in TiO2 metasurfaces, which are important for the structural colors to reach real-world industrial applications.
Journal ArticleDOI
All-dielectric metasurface for high-performance structural color.
Wenhong Yang,Shumin Xiao,Shumin Xiao,Qinghai Song,Qinghai Song,Yilin Liu,Yunkai Wu,Shuai Wang,Jie Yu,Jiecai Han,Din Ping Tsai +10 more
TL;DR: The authors fabricate a metasurface with high brightness and large gamut structured colors by combining a silicon metasURface with a refractive index matching layer, improving the brightness and the color purity significantly.
Journal ArticleDOI
Evidence of cooperative effect on the enhanced superconducting transition temperature at the FeSe/SrTiO3 interface.
Qinghai Song,Tianlun Yu,Xia Lou,Binping Xie,H. C. Xu,C. H. P. Wen,Qingqing Yao,Songyan Zhang,Xihua Zhu,Jiandong Guo,Rui Peng,Donglai Feng +11 more
TL;DR: The evidence of cooperation between intrinsic pairing interaction in FeSe and interfacial electron–phonon coupling to enhance the Tc at the FeSe/SrTiO3 interface is revealed.
Journal ArticleDOI
Random lasing in bone tissue
Qinghai Song,Shumin Xiao,Zhengbin Xu,Jingjing Liu,Xuanhao Sun,Vladimir P. Drachev,Vladimir M. Shalaev,Ozan Akkus,Young L. Kim +8 more
TL;DR: The numerical simulation shows that random lasers are extremely sensitive to subtle structural changes even at nanoscales and can potentially be an excellent tool for probing nanoscale structural alterations in real time as a novel spectroscopic modality.
