Stimulated Emission of Microcavity Exciton Polariton
The interaction of a bosonic or fermionic particle with a single bosonic field has been an important topic in the study of cavity quantumelectrodynamics. Experimental studies of this interaction have so far been studied in two systems, atoms inside a high Q cavity and quantum well excitons inside a microcavity. In this proceeding, we present results of photoluminescence and pump-probe experiments performed on the latter system. We show that amplification and attenuation of the probe beam (seed) can occur depending on the exciton density which show the bosonic feature of exciton polaritons and importance of exciton-acoustic phonon interaction at low temperature.
