摘　　要：从理论上研究了由一个单腔光力系统和一个辅助腔组成的耦合腔系统中光力诱导放大和慢光效应的特性。结果表明,如果采用高品质的辅助腔(具有很小的衰减速率),系统中探测场的强度可以得到显著放大。结果还发现,基于完美的光力诱导透明特性,该模型中的时间延迟很容易超过单腔光力系统中的时间延迟上限。此外,还研究了该系统中完美光力诱导吸收的有趣现象。该研究结果可以应用于现代光网络中的光传输。In a coupled-cavity system consisting of a single-cavity optomechanical system and an auxiliary cavity,we theoretically investigate the characteristics of optomechanically induced amplification and the slow light effect.The results show that if we adopt a high-quality auxiliary cavity(with a small decay rate),the strength of the probe field in the system can be strongly amplified.Based on the perfect optomechanically induced transparency,we also find that the time delay in this model can easily surpass its upper bound in the single-cavity optomechanical system.Additionally,the system is used to study the interesting phenomenon of perfect optomechanically induced absorption.We believe that the results can be used to control optical transmission in modern optical networks.
