Dynamic Topological Light Control in Reconfigurable Non-Hermitian Metastacks
Ryan Hogan, Zihan Lu, Han Peng +4
Metasurfaces often require complex lithography for dynamic optical control. To overcome this, we utilize a lithography-free, non-Hermitian planar metastack comprising a distributed…
Topological Quantum Interferometry
Tianyou Ying, Yufeng Zhou, Chengwei Pan +5
Structured light provides high-dimensional Hilbert spaces holding tremendous potential for fundamental quantum optics and quantum technologies. However, existing characterization m…
Efficient high-quality photon pair generation in modal phase-matched thin-film lithium niobate micro-ring resonators
Tingting Chen, Feihong Xue, Ryan Hogan +9
Efficient generation of high-quality photon pairs is essential for modern quantum technologies. Micro-ring resonator is an ideal platform for studying on-chip photon sources due to…
Topological Degeneracy Induced by Twisting
Han Peng, Qiang Wang, Meng Xiao +3
In recent years, twisting has emerged as a new degree of freedom that plays an increasingly important role in Bloch bands of various physical systems. However, there is currently a…
