An entropy-controlled objective chip for reflective confocal microscopy with subdiffraction-limit resolution
Jun He, Dong Zhao, Hong Liu +3
Planar lenses with optimized but disordered structures can focus light beyond the diffraction limit. However, these disordered structures have inevitably destroyed wide-field imagi…
High-order Photonic Cavity Modes Enabled 3D Structural Color
Hailong Liu, Hongtao Wang, Hao Wang +8
It remains a challenge to directly print three-dimensional arbitrary shapes that exhibit structural colors at the micrometer scale. Woodpile photonic crystals (WPCs) fabricated via…
Recent Advances in Tunable Metasurfaces: Materials, Design and Applications
Omar A. M. Abdelraouf, Ziyu Wang, Hailong Liu +6
Metasurfaces, a two-dimensional (2D) form of metamaterials constituted by planar meta-atoms, exhibit exotic abilities to freely tailor electromagnetic (EM) waves. Over the past dec…
Multistate Tuning of Third Harmonic Generation in Fano-Resonant Hybrid Dielectric Metasurfaces
Omar A. M. Abdelraouf, Aravind P. Anthur, Zhaogang Dong +6
Hybrid dielectric metasurfaces have emerged as a promising approach to enhancing near field confinement and thus achieving high optical nonlinearity using low loss dielectrics. Add…
High-Efficiency Ultra-Violet Dielectric Meta-Holograms with Antiferromagnetic Resonances
Kun Huang, Jie Deng, Hai Sheng Leong +4
Metasurfaces with spatially varying subwavelength structures enable full control of electromagnetic waves over a wide spectrum. High-efficiency metasurfaces, especially in a transm…
Flat Helical Nanosieves
Shengtao Mei, Muhammad. Qasim. Mehmood, Sajid Hussain +7
Compact and miniaturized devices with flexible functionalities are always highly demanded in optical integrated systems. Plasmonic nanosieve has been successfully harnessed as an u…
Continuously Shaping Orbital Angular Momentum with an Analog Optical Vortex Transmitter
Kun Huang, Hong Liu, M. Q. Mehmood +4
Dynamic generation of obitial angular momentum (OAM) of light has enabled complex manipulation of micro-particles, high-dimension quantum entanglement and optical communication. We…
Subwavelength focusing of azimuthally polarized beams with vortical phase in dielectrics by using an ultra-thin lens
Kun Huang, Huapeng Ye, Hong Liu +3
We demonstrate that a planar and ultrathin binary lens can focus an azimuthally polarized beam with vortical phase (APV) to a subwavelength spot of transverse polarization. The res…
