38-Photonic Switching Devices by Means of Polariton Redistribution in TMDC’s: A comparative analysis between Ψ-shaped and Y-shaped channel guides

Image 36 of 44

Using the Langevin equation, we numerically model the stochastic diffusive dynamics of a dipolariton gas in an optical microcavity with a MoSe2-WS2 TMDC bilayer. The dipolariton particles, which are a three-way mixture of direct exciton, indirect exciton and cavity photon, are considered to be confined in a Ψ-shaped channel guide (with and without a buffer branch) as well as a Y-shaped channel guide. By variance of channel parameters such as electric field angle and electric driving force, we are able to study the resulting dipolariton branch redistributions. We are able to attain performances of >90% in both channel geometries for particular channel parameters, while making comparative analyses between the varying channel geometries. Our results open the route towards the development of room temperature based photonic switching devices for various channel guide geometries. View or download a PDF version of this poster.
