Valley optoelectronics based on meta-waveguide photodetectors
Chi Li, Kaijian Xing, Wenhao Zhai +10
In transition metal dichalcogenides, the valley degree of freedom directly couples valley-polarised excitons - excited by circularly polarised light - to valley-dependent chiral ph…
Negative reflection of polaritons at the nanoscale in a low-loss natural medium
Gonzalo Alvarez-Perez, Jiahua Duan, Javier Taboada-Gutierrez +10
Negative reflection occurs when light is reflected towards the same side of the normal to the boundary from which it is incident. This exotic optical phenomenon, which provides a n…
Tailoring topological transition of anisotropic polaritons by interface engineering in biaxial crystals
Yali Zeng, Qingdong Ou, Lu Liu +11
Polaritons in polar biaxial crystals with extreme anisotropy offer a promising route to manipulate nanoscale light-matter interactions. The dynamical modulation of their dispersion…
Hybridized hyperbolic surface phonon polaritons at α-MoO3 and polar dielectric interfaces
Qing Zhang, Qingdong Ou, Guangwei Hu +5
Surface phonon polaritons (SPhPs) in polar dielectrics offer new opportunities for infrared nanophotonics due to sub-diffraction confinement with low optical losses. Though the pol…
Observation of topological polaritons and photonic magic angles in twisted van der Waals bi-layers
Guangwei Hu, Qingdong Ou, Guangyuan Si +9
Twisted two-dimensional bi-layers offer exquisite control on the electronic bandstructure through the interlayer rotation and coupling, enabling magic-angle flat-band superconducti…
Topological-darkness-assisted phase regulation for atomically thin meta-optics
Yingwei Wang, Zi-Lan Deng, Dejiao Hu +13
Two-dimensional (2D) noble-metal dichalcogenides have emerged as a new platform for the realization of versatile flat optics with a considerable degree of miniaturization. However,…
