Tuning the Energy of a Polariton Condensate via Bias-Controlled Rabi Splitting

Abstract

An exciton polariton (a photon, electron, and a hole in a bound state, behaving as a boson) is a building block for a condensate that emits coherent light. On-chip manipulation of such condensates is an essential step toward polariton-based quantum information devices and lasers. In this work the energy of a polariton condensate in a high-finesse GaAs microcavity is tuned, bringing into reach polariton condensate devices that can be controlled by applied electrical bias.
