Abstract:
Microcavity exciton-polaritons results from the admixture of cavity photons and excitons in the strong coupling regime. Due to their hybrid nature, polaritons are a promising solid-state platform for both fundamental studies on light-matter interaction and applications in quantum and opto-electronics technologies. In this thesis, optically imprinted graphs of interacting polariton condensates are proposed and demonstrated to simulate universal spin models whose ground state brings about the solution of a bespoken optimisation task. The establishment, control and tailoring of a complex network of interactions across the graphs' nodes is an essential ingredient to map complex optimisation tasks to a polariton graph. Here, a method is proposed to quantify and measurecoupling strength between a pair of polariton condensates as a function of their physical separation. Furthermore, this thesis also outlines how the coupling is influenced by optically injecting a non-homogeneously polarised polariton graph.
