Generation of high-quality single-photon sources in cavity optomagnonics
-
Abstract
We propose a scheme for generating high-quality single-photon sources utilizing the conventional photon blockade (CPB) effect in a cavity optomagnonic system with Kerr nonlinearity. The realization of the CPB effect depends on both the Kerr nonlinearity and the Kerr-like nonlinearity of the optical cavity converted by the magneto-optical coupling. The CPB effect can be realized in a cavity optomagnonic system with weak magneto-optical coupling by modulating the strength of the Kerr nonlinearity. Notably, our scheme supports photon blockade in both the strong and weak Kerr nonlinear regimes, which broadens the range of experimental parameters. Furthermore, we explore the parameter regimes where CPB cannot be achieved due to the combined effects of magneto-optical coupling and Kerr nonlinearity. Meanwhile, we determine the optimal driving amplitude region for generating high-quality single-photon sources. This work not only provides a novel route for realizing the CPB effect but also establishes a versatile platform for producing single-photon sources with high purity and brightness.
