Demonstration of a genetic-algorithm-optimized cavity-based waveguide crossing
Pengfei Xu, Yanfeng Zhang, Zengkai Shao +2
A compact, single-etch silicon photonics waveguide crossing based on low quality factor cavity and optimized by a genetic algorithm is demonstrated. The device has 0.1~0.3 dB inser…
On-chip radially and azimuthally polarized vortex beam generation utilizing shallow-etched gratings
Zengkai Shao, Jiangbo Zhu, Yanfeng Zhang +2
Cylindrical vector vortex (CVV) beams, complex light fields that exhibit a vector nature and carry quantized orbital angular momentum states, have been widely investigated due to t…
Hybrid light-emitting polymer/SiNx platform for photonic integration
Zeming Fan, Zeru Wu, Yujie Chen +4
Organic semiconductors have potentials for a broad range of applications; however, it is difficult to be integrated with traditional inorganic material to meet the need of further…
Orbital-angular-momentum mode-group multiplexed transmission over a graded-index ring-core fiber based on receive diversity and maximal ratio combining
Junwei Zhang, Guoxuan Zhu, Liu Jie +5
An orbital-angular-momentum (OAM) mode-group multiplexing (MGM) scheme based on a graded-index ring-core fiber (GIRCF) is proposed, in which a single-input two-output (or receive d…
Spin-orbit interaction of light induced by transverse spin angular momentum engineering
Zengkai Shao, Jiangbo Zhu, Yujie Chen +2
We report the first demonstration of a direct interaction between the extraordinary transverse spin angular momentum in evanescent waves and the intrinsic orbital angular momentum…
Silicon nitride metalenses for unpolarized high-NA visible imaging
Zhi-Bin Fan, Zeng-Kai Shao, Ming-Yuan Xie +6
As one of nanoscale planar structures, metasurface has shown excellent superiorities on manipulating light intensity, phase and/or polarization with specially designed nanoposts pa…
