High-efficiency grating couplers for pixel-level flat-top beam generation
Zhong-Tao Tian, Ze-Peng Zhuang, Zhi-Bin Fan +2
We demonstrate a kind of grating coupler that generates high quality flat-top beam with a small beamwidth from photonic integrated circuits into free-space. The grating coupler is…
Topological photonic crystals: physics, designs and applications
Guo-Jing Tang, Xin-Tao He, Fu-Long Shi +3
The recent research of topological photonics has not only proposed and realized novel topological phenomena such as one-way broadband propagation and robust transport of light, but…
Ideal Nodal Rings of One-Dimensional Photonic Crystals in the Visible Region
Wei-Min Deng, Ze-Min Chen, Meng-Yu Li +4
Three-dimensional (3D) artificial metacrystals host rich topological phases, such as Weyl points, nodal rings and 3D photonic topological insulators. These topological states enabl…
Topologically protected valley-dependent quantum photonic circuits
Yang Chen, Xin-Tao He, Yu-Jie Cheng +7
Topological photonics has been introduced as a powerful platform for integrated optics, since it can deal with robust light transport, and be further extended to the quantum world.…
Frequency-dependent topological phases and photonic detouring in valley photonic crystals
Guo-Jing Tang, Xiao-Dong Chen, Fu-Long Shi +3
Here, the frequency degree of freedom is introduced into valley photonic crystals with dual band gaps. Based on the high-order plane wave expansion model, we derive an effective Ha…
Transmissive Metagrating for Arbitrary Wavefront Shaping Over the Full Visible Spectrum
Zi-Lan Deng, Xuan Ye, Hao-Yang Qiu +10
Metagratings have been shown to form an agile and efficient platform for extreme wavefront manipulation, going beyond the limitations of gradient metasurfaces. Previous approaches…
