Polariton Circuits

In this project we investigate the fundamental properties of spinor polariton condensates towards polariton circuits. We aim to develop the toolbox for all-optical writing of polariton circuits on planar microcavities and utilize the spin of polaritons in configuration that bear applications in all optical switching, optical routing, and volatile optical memory components.
