Interaction between a semiconductor quantum dot microcavity and a squeezed vacuum in a cavity: effects on the photon statistics

The interaction between a squeezed vacuum and a semiconductor quantum dot microcavity is studied. The influence of this interaction on the photon statistics, one measurable quantity, is investigated in the presence of the electron–phonon interaction. When the system interacts with the squeezed vacuum, the non-classical features of the emitted photons are studied. It turns out that the photon counting statistics depend on the detuning and temperature. The emitted photons also exhibit non-classical features such as anti-bunching, and their non-classical features depend on the degree of squeezing. Moreover, it is found that the stronger the squeezed vacuum, the weaker the non-classical features in the photon counting statistics. (paper)
