One-Mode Subharmonic Generator Coupled to Thermal Reservoir

Abstract

We have analyzed the squeezing and statistical properties of the light produced by one-mode subharmonic generator coupled to thermal reservoir. We first obtain c-number Langevin equation with the aid of the master equation. The solution of the resulting c-number Langevin equation is then used to determine the anti-normally characteristic function. With the aid of the resulting characteristic function, we obtain the Q function and the density operator. In addition, employing the Q function along with the density operator, we calculate the mean photon number, the variance of the photon number, the power spectrum, the photon number distribution, and the quadrature variance. We found that the squeezing of the one-mode subharmonic generator indeed affected by the thermal light.
