Photon excitation and photon-blockade effects in optomagnonic microcavities

Controlling the interaction between the spin wave and the electromagnetic field is an important issue of optoelectronics. The effect of photon blockade is to indicate the interaction that prevents multiple photons from entering the cavity simultaneously, which is the pivotal effect to achieve the photons at the quantum level. Here in this study, we investigate an effective way of photon controlling and find the photon-blockade effect in the hybrid optomagnonic microcavity. Specifically, we show that the magnons and photons in both transverse electric and transverse magnetic modes can be converted into the supermode photons under the Kerr effect. Also the correlation function of the photons is analytically studied, which shows the asymmetry behavior for the two different supermodes. This proposed system opens up a route to control the optical mode in hybrid microresonators, which are important for advanced quantum technologies.
