  Using a computational approach based on the driven diffusion equation for
dipolariton wave packets, we simulate the diffusive dynamics of dipolaritons in
an optical microcavity embedded with a transition-metal dichalcogenide (TMDC)
heterogeneous bilayer encompassing a {\Psi}-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
{\Psi}-shaped channel. We also consider the propagation of dipolaritons in the
presence of a buffer in the {\Psi}-shaped channel and study resulting changes
in efficiency. By our consideration of a geometrically novel dipolariton
channel guide, we introduce novel designs for optical routers at room
temperature as well as replicate the dipolariton redistribution efficiencies of
previously proposed polaritronic applications.
