Exploiting topological ideas has been a major theme in modern photonics, which provides unprecedented opportunities to design photonic devices with robustness against defects and f…
A perspective of twisted photonic structures
Jialin Chen, Xiao Lin, Mingyuan Chen +3
Moire superlattices-twisted van der Waals (vdW) structures with small angles-are attracting increasing attention in condensed matter physics, due to important phenomena revealed th…
Non-Hermitian skin effect and delocalized edge states in photonic crystals with anomalous parity-time symmetry
Qinghui Yan, Hongsheng Chen, Yihao Yang
Non-Hermitian skin effect denotes the exponential localization of a large number of eigen-states in a non-Hermitian lattice under open boundary conditions. Such a non-Hermiticity-i…
Polarization-Orthogonal Nondegenerate Plasmonic Higher-Order Topological States
Yuanzhen Li, Su Xu, Zijian Zhang +10
Photonic topological states, providing light-manipulation approaches in robust manners, have attracted intense attention. Connecting photonic topological states with far-field degr…
Topological chiral edge states in deep-subwavelength valley photonic metamaterials
Rui Xi, Qiaolu Chen, Qinghui Yan +5
Topological valley photonics has emerged as a new frontier in photonics with many promising applications. Previous valley boundary transport relies on kink states at internal bound…
Unconventional Weyl exceptional contours in non-Hermitian photonic continua
Qinghui Yan, Qiaolu Chen, Li Zhang +3
Unconventional Weyl points with topological charges higher than 1 can transform into various complex unconventional Weyl exceptional contours under non-Hermitian perturbations. How…
A Brewster route to Cherenkov detectors
Xiao Lin, Hao Hu, Sajan Easo +10
The Cherenkov effect enables a valuable tool, known as the Cherenkov detector, to identify high-energy particles via the measurement of the Cherenkov cone. However, the sensitivity…
Diffusive Topological Transport in Spatiotemporal Thermal Lattices
Guoqiang Xu, Yihao Yang, Xue Zhou +3
Topological insulating phases are usually found in periodic lattices stemming from collective resonant effects, and it may thus be expected that similar features may be prohibited…
Second-order correlation function supported optical sensing for particle detection
T. Wang, C. Jiang, J. Zou +6
We propose a new sensing method based on the measurement of the second-order autocorrelation of the output of micro- and nanolasers with intensity feedback. The sensing function is…
Quasi-BIC laser enabled by high-contrast grating resonator for gas detection
H. Zhang, T. Wang, J. Tian +9
In this work, we propose and numerically investigate a two-dimensional microlaser based on the concept of bound states in the continuum (BIC). The device consists of a thin gain la…
Emerging chiral optics from chiral interfaces
Xinyan Zhang, Yuhan Zhong, Tony Low +2
Twisted atomic bilayers are emerging platforms for manipulating chiral light-matter interaction at the extreme nanoscale, due to their inherent magnetoelectric responses induced by…
Acoustic non-Hermitian skin effect from twisted winding topology
Li Zhang, Yihao Yang, Yong Ge +11
The recently discovered non-Hermitian skin effect (NHSE) manifests the breakdown of current classification of topological phases in energy-nonconservative systems, and necessitates…
