We report on a theoretical investigation of guided polariton states arising from the strong coupling between a single quantum-well exciton and a Bloch Surface Wave in a multi-layered structure. We show that the polariton Rabi splitting can be increased by almost 40% as compared to that achievable in a similar structure made in a conventional planar microcavity. Moreover, we theoretically demonstrate that by simple engineering of the sample surface with oxide deposition, one can obtain 1D polaritons propagating within the structure. The latter result shows the usefulness of our proposed device as a key component for the realization of "polaritonic integrated circuits".

Abstract
We report on a theoretical investigation of guided polariton states arising from the strong coupling between a single quantum-well exciton and a Bloch Surface Wave in a multi-layered structure. We show that the polariton Rabi splitting can be increased by almost 40% as compared to that achievable in a similar structure made in a conventional planar microcavity. Moreover, we theoretically demonstrate that by simple engineering of the sample surface with oxide deposition, one can obtain 1D polaritons propagating within the structure. The latter result shows the usefulness of our proposed device as a key component for the realization of "polaritonic integrated circuits".I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
