| Popis: | Exciton-dipolaritons are investigated as a platform for realizing working elements of a polaritronic transistor. Exciton-dipolaritons are three-way superposition of cavity photons, direct and indirect excitons in a bilayer semiconducting system embedded in an optical microcavity. Using the forced diffusion equation for dipolaritons, we study the room-temperature dynamics of dipolaritons in a transition metal dichalcogenide (TMD) heterogeneous bilayer. Specifically, we considered a MoSe$_2$-WS$_2$ heterostructure, where a Y-shaped channel guiding the dipolariton propagation is produced. We demonstrate that polaritronic signals can be redistributed in the channels by applying a driving voltage in an optimal direction. Our findings open a route towards the design of an efficient room-temperature dipolariton-based optical transistor. Comment: 23 pages, 9 figures |
