Abstract
This paper numerically explores the general characteristics of active optomechanics, where optical gain directly impacts mechanical motion on lasing dynamics. The study investigates the effects of mechanical oscillation on macroscopic lasers, including the introduction of multiple unstable lasing regimes, laser frequency shifts, spectral broadening, and degraded frequency stability. Reducing the optical gain to a single active atom reveals quantum atom-cavity and photon-phonon interactions, leading to the emission of nonclassical photons and the generation of nonclassical photon-phonon pairs. The research extends cavity optomechanics to an active approach, suggesting potential applications in optomechanical light sources for photonic integrated circuits, on-chip quantum communication, and biosensing.
