Abstract

This study presents a theoretical investigation of magnomechanically induced transparency, Fano resonance, and slow/fast light phenomena within a hybrid optomagnomechanical system. The system consists of a mechanical membrane within a cavity and a ferrimagnetic crystal with a magnon squeezing mode that couples directly to a microwave cavity mode through magnetic dipole interaction and indirectly to an optical cavity through the crystal's deformation displacement. The optical cavity is influenced by the mechanical displacement, which is driven by magnetostrictive forces through radiation pressure. The interactions among photon, phonons, magnons, and microwave within the cavity give rise to optomechanically induced transparency (OMIT), magnomechanically induced transparency (MMIT) and magnon-induced transparency (MIT). We analyze how the presence of magnon squeezing modifies the absorption and dispersion properties of the optical spectrum. Additionally, the emergence of Fano resonance via photon-phonon coupling in the presence of the magnon squeezing is examined. By tuning the microwave-magnon interactions and the magnon squeezing parameters, we enhance slow/light effects. Our results aim to contribute to the development of quantum information processing technologies.
