Flexible Coherent Optical Access: Architectures, Algorithms, and Demonstrations
Ji Zhou, Zhenping Xing, Haide Wang +9
To cope with the explosive bandwidth demand, significant progress has been made in the ITU-T standardization sector to define a higher-speed passive optical network (PON) with a 50…
Optical vortices enabled by structural vortices
Yuanfeng Liu, Le Zhou, Mengfan Guo +7
The structural symmetry of solids plays an important role in defining their linear and nonlinear optical properties. The quest for versatile, cost-effective, large-scale, and defec…
Spin photonics on chip based on a twinning crystal metamaterial
Yan Li, Jingbo Sun, Yongzheng Wen +2
Two-dimensional photonic circuits with high capacity are essential for a wide range of applications in next-generation photonic information technology and optoelectronics. Here we…
Timing Recovery for Point-to-Multi-Point Coherent Passive Optical Networks
Ji Zhou, Jinyang Yang, Haide Wang +2
We propose a timing recovery for point-to-multi-point coherent passive optical networks. The results show that the proposed algorithm has low complexity and better robustness again…
