Tunable magnomechanically and optomechanically induced transparency in a cavity opto-magnomechanical system

Abstract We demonstrate multiple transparency windows in a cavity opto-magnomechanical system containing a ferromagnetic material yttrium iron garnet (YIG) crystal. The probe output spectrum reveals the simultaneous emergence of three distinct phenomena: magnon-induced transparency (MIT) arising from microwave–magnon coupling; magnomechanically induced transparency (MMIT) through phonon–magnon interaction, and optomechanically induced transparency (OMIT) mediated by optical cavity–photon coupling. Crucially, these transparency features demonstrate dynamic tunability through precise manipulation of the number of interacting modes and coupling strengths. Our study reveals the effects of magnon–microwave and optomechanical coupling on probe results and the role of quantum interference mechanisms in a resonant system. Moreover, the fast-slow light effect can be enhanced and switched by choosing appropriate coupling parameters. Our work has potential applications in multi-band quantum storage and multi-channel photonic information processing devices.
