Journal ArticleDOI
Photonic spin hall effect at metasurfaces
TL;DR: A strong photonic SHE resulting in a measured large splitting of polarized light at metasurfaces is reported, which may provide a route for exploiting the spin and orbit angular momentum of light for information processing and communication.
Journal ArticleDOI
Amino-acid- and peptide-directed synthesis of chiral plasmonic gold nanoparticles
Hye-Eun Lee,Hyo-Yong Ahn,Jungho Mun,Yoon Young Lee,Minkyung Kim,Nam Heon Cho,Kiseok Chang,Wook Sung Kim,Wook Sung Kim,Junsuk Rho,Ki Tae Nam +10 more
TL;DR: A strategy for synthesizing chiral gold nanoparticles that involves using amino acids and peptides to control the optical activity, handedness and chiral plasmonic resonance of the nanoparticles is developed and it is anticipated that this strategy will aid in the rational design and fabrication of three-dimensional chiral nanostructures for use in plAsmonic metamaterial applications.
Journal ArticleDOI
Photoinduced handedness switching in terahertz chiral metamolecules
Shuang Zhang,Jiangfeng Zhou,Yong-Shik Park,Junsuk Rho,Ranjan Singh,Sunghyun Nam,Abul Kalam Azad,Hou-Tong Chen,Xiaobo Yin,Xiaobo Yin,Antoinette J. Taylor,Xiang Zhang,Xiang Zhang +12 more
TL;DR: The experimentally demonstrated optical switching effect of handedness switching in metamaterials, a new class of custom-designed composites with deep subwavelength building blocks, in response to external optical stimuli allows electromagnetic control of the polarization of light.
Journal ArticleDOI
Spherical hyperlens for two-dimensional sub-diffractional imaging at visible frequencies
Junsuk Rho,Ziliang Ye,Yi Xiong,Xiaobo Yin,Xiaobo Yin,Zhaowei Liu,Zhaowei Liu,Hyeunseok Choi,Guy Bartal,Xiang Zhang,Xiang Zhang +10 more
TL;DR: The spherical hyperlens is designed with flat hyperbolic dispersion that supports wave propagation with very large spatial frequency and yet same phase speed, which allows it to resolve features down to 160 nm, much smaller than the diffraction limit at visible wavelengths.
Journal ArticleDOI
Experimental realization of three-dimensional indefinite cavities at the nanoscale with anomalous scaling laws
TL;DR: In this paper, a three-dimensional metal-dielectric optical cavity with an ultra-high optical index of 17.4 was reported, and the resonant frequency of the cavity is constant and independent of its size.
