Demonstration of negative refraction induced by synthetic gauge fields
Yihao Yang, Yong Ge, Rujiang Li +7
The phenomenon of negative refraction generally requires negative refractive indices or phase discontinuities, which can be realized using metamaterials or metasurfaces. Recent the…
Negative refraction of ultra-squeezed in-plane hyperbolic designer polaritons
Qiaolu Chen, Yihao Yang, Li Zhang +6
The in-plane negative refraction of high-momentum (i.e., high-k) photonic modes could enable many applications such as imaging and hyperlensing in a planar platform at deep-subwave…
Controlling Cherenkov threshold with nonlocality
Hao Hu, Xiao Lin, Jingjing Zhang +4
Cherenkov radiation is generally believed to be threshold-free in hyperbolic metamaterials owing to the extremely large photonic density of states in classical local framework. Whi…
Observation of an unpaired photonic Dirac point
Gui-Geng Liu, Peiheng Zhou, Yihao Yang +7
At photonic Dirac points, electromagnetic waves are governed by the same equations as two-component massless relativistic fermions. However, photonic Dirac points are known to occu…
Valley-Hall photonic topological insulators with dual-band kink states
Qiaolu Chen, Li Zhang, Mengjia He +6
Extensive researches have revealed that valley, a binary degree of freedom (DOF), can be an excellent candidate of information carrier. Recently, valley DOF has been introduced int…
Broadband negative refraction of highly squeezed hyperbolic graphene plasmons
Jing Jiang, Xiao Lin, Baile Zhang
Negative refraction of highly squeezed polaritons is a fundamental building block for nanophotonics, since it can enable many unique applications, such as deep-subwavelength imagin…
