Quantum Statistical and Squeezing Properties in a Semiconductor Cavity QED

Abstract

We consider a quantum well with one exciton in a microcavity that initially contains photons and is coupled to a one-mode squeezed vacuum reservoir. The solution of the quantum Langevin equation is used to investigate the intensity, second-order correlation function, intensity spectrum, and quadrature squeezing of the exciton mode in the low-excitation regime. Although the initial cavity photons increase the intensity of the exciton mode, they have an adverse effect on the quadrature squeezing. We also demonstrate that the exciton mode exhibits quadrature squeezing, with the amount of squeezing increased by the input squeezed light.
