Exciton-dipolaritons are investigated as a platform for realizing workingelements of a polaritronic transistor. Exciton-dipolaritons are three-waysuperposition of cavity photons, direct and indirect excitons in a bilayersemiconducting system embedded in an optical microcavity. Using the forceddiffusion equation for dipolaritons, we study the room-temperature dynamics ofdipolaritons in a transition metal dichalcogenide (TMD) heterogeneous bilayer.Specifically, we considered a MoSe$_2$-WS$_2$ heterostructure, where a Y-shapedchannel guiding the dipolariton propagation is produced. We demonstrate thatpolaritronic signals can be redistributed in the channels by applying a drivingvoltage in an optimal direction. Our findings open a route towards the designof an efficient room-temperature dipolariton-based optical transistor.
