Abstract

Quantum fluctuations of a system formed by two quantum wells inside a microcavity are investigated. The noise spectrum and the autocorrelation function are analyzed, and analytical expressions are derived. It is shown here that the noises are equally balanced over direct and indirect exciton thermal baths. The double quantum well system induces more fluctuations compared to the system formed by a single quantum well inside a microcavity. Unlike the latter system, the autocorrelation function of the cavity depends on the exciton thermal bath populations. It turns out that the photon detection probability is affected by coupling with the indirect exciton thermal bath.
