  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.
