External field effect on the statistical behavior of a cavity containing quantum wells

Semiconductor microcavities with quantum wells are known for the richness of the optical properties that can produce. They have exceptional optical proprieties with several

potential applications such as in quantum computing and gravitational wave detection. In these heterostructures, polaritons are quasi-particles that can be formed via a strong interaction between light and excitons. Here, we explore the effect of an externally squeezed field applied to a cavity containing a pair of coupled quantum wells. This system gives rise to other quasi-particles named dipolaritons: a combination of polaritons and indirect excitons. We show that a strong squeezing of light can be achieved for particular parameters of the system. Good resistance to thermal baths temperature is also noted, especially at total resonance. The autocorrelation function shows super-Poissonian statistics, the signature of a bunching effect where the oscillation amplitudes are higher in the non-resonant case. For weak coupling, the oscillatory behavior of the correlation function disappears with a very small variation near the unit.
