Exciton-polariton flows in cross-dimensional junctions

Hugo Pierre Alexandre Flayac

We study the nonequilibrium exciton-polariton condensation in 1D to 0D and 1D to quasi-2D junctions by means of non-resonant spectroscopy. The shape of our potential landscape allows to probe the resonant transmission of a propagating condensate between a ...

Wideband H-plane dielectric horn antenna

Juan Ramon Mosig, Maria Garcia Vigueras, Lei Wang, Marcos Alvarez Folgueiras

By flaring a dielectric waveguide in the H-plane, an H-plane dielectric horn is formed, which could be directly excited by an SIW feed. However, matching and radiation performances are poor due to the thinness of the substrate. To improve these performance ...
