摘　　要：为了在腔磁力系统中实现可控的磁子诱导透明、磁力诱导透明、光放大以及快慢光传播,建立了一个腔磁力混合系统模型.该模型由含有1个钇铁石榴石(YIG)球的增益腔组成.该模型利用强驱动来驱动YIG球,利用弱探测场探测微波腔.研究表明,通过选取最优增益和调节腔-磁耦合强度、磁-力耦合强度可以实现可控的磁子诱导透明、磁力诱导透明、光放大以及快慢光传播.该研究结果可为量子信息操纵、量子信息存储和灵敏光开关的研究提供参考.A cavity magnomechanical hybrid system model was developed to obtain controllable magnon-induced transparency,magnomechanical-induced transparency,optical amplification,and fast-slow light propagation in the system.The model consists of a gain cavity comprising a yttrium iron garnet(YIG)sphere,which is driven by a strong driving field,while a weak probing field is utilized to detect the microwave cavity.The study reveals that by optimizing the gain,adjusting the cavity-magnon coupling strength,and modulating the magnomechanical coupling strength,controllable magnon-induced transparency,magnomechanical-induced transparency,optical amplification,and fast-slow light propagation can be achieved.These findings have significant implications for quantum optical manipulation,quantum information storage,and the development of sensitive optical switches.
