39. Dipolariton Propagation In A Van Der Waals Tmdc With Ψ-shaped Channel Guides And Buffered Channel Branches
Using a computational approach based on the driven diffusion equation for a dipolariton wave packet, we simulate the diffusive dynamics of dipolaritons in an optical microcavity embedded with a transition metal dichalcogenide (TMDC) heterogeneous bilayer encompassing a Ψ-shaped channel. By considering exciton-dipolaritons, which are a three way superposition of direct excitons, indirect excitons and cavity photons, we are able to drive the dipolaritons in our system by the use of an electric voltage and investigate their diffusive properties. More precisely, we study the propagation of dipolaritons present in a MoSe2-WS2 heterostructure, where the dipolariton propagation is guided by a Ψ-shaped channel. By our consideration of a geometrically novel dipolariton channel guide, we are able to replicate the dipolariton redistribution efficiencies of previously proposed polaritronic applications as well introduce novel designs for optical routers at room temperature.
