Effects of linear and quadratic dispersive couplings on optical squeezing in an optomechanical system
arXiv:1509.08058 · doi:10.1103/PhysRevA.92.033824
Abstract
A conventional optomechanical system is composed of a mechanical mode and an optical mode interacting through a linear optomechanical coupling (LOC). We study how the presence of quadratic optomechanical coupling (QOC) in the conventional optomechanical system affects the system's stability and optical quadrature squeezing. We work in the resolved side-band limit with a high quality factor mechanical oscillator. In contrast to the conventional optomechanical systems, we find that strong squeezing of the cavity field can be achieved in presence of QOC along with LOC at lower pump powers and at higher bath temperatures. Using detailed numerical calculations we also find that there exists an optimal QOC where one can achieve maximum squeezing.
