Control over cavity exciton polaritons in monolayer semiconductors
Zhi Wang, Li He, Bumho Kim +1
Integrating two-dimensional van der Waals materials with optical cavities has revealed a fascinating platform to study exciton-polariton physics. Manipulating exciton polaritons of…
Direct Observation of Landau Levels in Silicon Photonic Crystals
Maria Barsukova, Fabien Grisé, Zeyu Zhang +7
We experimentally observe photonic Landau levels that arise due to a strain-induced pseudomagnetic field in a silicon photonic crystal slab. The Landau levels are dispersive (i.e.,…
Observation of Floquet Chern insulators of light
Jicheng Jin, Li He, Jian Lu +5
The field of topological photonics studies unique and robust photonic systems that are immune to defects and disorders due to the protection of their underlying topological phases.…
3D nonlinear optical metamaterials from twisted 2D van der Waals interfaces
Bumho Kim, Jicheng Jin, Zhi Wang +4
To enable new nonlinear responses, metamaterials are created by organizing structural units (meta-atoms) which are typically on the scale of about a hundred nanometers. However, tr…
