Phyllotaxis-inspired Nanosieves with Multiplexed Orbital Angular Momentum
Zhongwei Jin, David Janoschka, Junhong Deng +15
Nanophotonic platforms such as metasurfaces, achieving arbitrary phase profiles within ultrathin thickness, emerge as miniaturized, ultracompact and kaleidoscopic optical vortex ge…
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…
Collective near-field coupling in infrared-phononic metasurfaces for nano-light canalization
Peining Li, Guangwei Hu, Irene Dolado +10
Polaritons, coupled excitations of photons and dipolar matter excitations, can propagate along anisotropic metasurfaces with either hyperbolic or elliptical dispersion. At the tran…
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…
Moiré Hyperbolic Metasurfaces
Guangwei Hu, Alex Krasnok, Yarden Mazor +2
Recent advances in twistronics of low-dimensional materials, such as bilayer graphene and transition-metal dichalcogenides, have enabled a plethora of unusual phenomena associated…
Suppressing Material Loss for Functional Nanophotonics Using Bandgap Engineering
Mingsong Wang, Alex Krasnok, Sergey Lepeshov +6
All-dielectric nanoantennas have recently opened exciting opportunities for functional nanophotonics, owing to their strong optical resonances along with low material loss in the n…
