- 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.
- Abstract:
- 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.
