    Abstract

    Exciton-polaritons (polaritons) are hybrid bosonic quasiparticles that appear in the strong coupling regime of light-matter interaction. Polariton condensation in inorganic microcavities is of great interest due to potential optoelectronic applications such as optical switches, transistors and recently proposed analogue simulators [1]. In this regard, polariton condensate lattices of arbitrary geometries, can be used to solve real word problems that otherwise require huge computing power. Engineering of the extended condensate wavefunction relies on the spatial configuration of the lattice imposed by the optical source. Consequently, the lattice geometry dictates the coupling strength between adjacent condensate nodes. The influence of lattice geometry on coupling strength effectively limits the range of systems that can be simulated. Therefore, it is highly desirable to control the coupling strength between condensates independently of the lattice geometry. The simplest element of the lattice is the dyad - 2 spatially separate polariton condensates. The interaction between the condensates leads to phase locking which can be confirmed by imaging of the sample photoluminescence in real and reciprocal space.
