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 sideband 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 the 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.
