A new type of infrared polaritons at the surface of bulk crystals

An international team has reported in Nature the first observation of ghost polaritons, which are a new form of surface waves carrying nanoscale light strongly coupled with material oscillations and featuring highly collimated ...

Non-linear effects in coupled optical microcavities

Scientists from the Faculty of Physics of the University of Warsaw have demonstrated exciton-polariton lasing and parametric scattering of exciton-polaritons in a system of coupled optical microcavities. The results have ...

Better integrated circuits with glide symmetry

Surface plasmon polaritons (SPPs) are highly localized surface waves on the interface between metal and dielectric in the optical frequency band. SPPs do not naturally exist in the microwave and terahertz frequencies, so ...
