Collective Mie Exciton-Polaritons in an Atomically Thin Semiconductor
Shaojun Wang, T. V. Raziman, Shunsuke Murai +6
Optically induced Mie resonances in dielectric nanoantennas feature low dissipative losses and large resonant enhancement of both electric and magnetic fields. They offer an altern…
A 20-Gbps Beam-steered Infrared Wireless Link Enabled by a Passively Field-programmable Metasurface
Jianou Huang, Chao Li, Yu Lei +7
Beam steering is one of the main challenges in energy-efficient and high-speed infrared light communication. To date, active beam-steering schemes based on a spatial light modulato…
Exciton diffusion and annihilation in nanophotonic Purcell landscapes
T. V. Raziman, C. Peter Visser, Shaojun Wang +2
Excitons spread through diffusion and interact through exciton-exciton annihilation. Nanophotonics can counteract the resulting decrease in light emission. However, conventional en…
Impact of indirect transitions on valley polarization in WS and WSe
Rasmus H. Godiksen, Shaojun Wang, T. V. Raziman +2
Controlling the momentum of carriers in semiconductors, known as valley polarization, is a new resource for optoelectronics and information technologies. Materials exhibiting high…
Enhanced light emission by magnetic and electric resonances in dielectric metasurfaces
Shunsuke Murai, Gabriel W. Castellanos, T. V. Raziman +2
We demonstrate an enhanced emission of high quantum yield molecules coupled to dielectric metasurfaces formed by periodic arrays of polycrystalline silicon nanoparticles. Radiative…
