Exciton-polariton integrated circuits

Abstract

We show that logical signals encoded in bistable states in semiconductor microcavities can be generated and controlled electronically by exploiting the electrical sensitivity of Tamm-plasmon--exciton-polariton modes. The signals can be transported along polariton neurons, created with a patterned metal surface. Using the Gross-Pitaevskii equations, we simulate an electrically controlled transistor and find that high repetition rates (10 GHz) are possible.
