In a recent issue of Science, Moore Foundation grantee Dimtri Basov and colleagues discuss controlling light in atomically thin two-dimensional materials using hybrid particles called polaritons. Basov is an experimental investigator in the foundation's Emergent Phenomena in Quantum Systems initiative.
Polaritons form when light is coupled with electricity or magnetism. Although these particles originate from different physical phenomena at different wavelengths of light, they exhibit nearly all optical phenomena found in solids.
In nanoscale two-dimensional materials such as graphene, polaritons can be steered to detect, harvest, emit, propagate and modulate light with unprecedented control.
By controlling polaritons in various two-dimensional materials, opportunities arise for a exciting new opportunities to focus light at the nanoscale, such as imaging below the diffraction limit.
