Abstract

We theoretically demonstrate optomechanically induced transparency (OMIT) and its related coherent optical propagation properties such as fast and slow light effects in a cavity optomechanical system driven by a weak coherent phonon pump for suitable parametric and detuning regimes. The probe transmission spectrum experiences different processes under different detuning regimes, and the numerical simulations indicating a tunable and controllable fast-to-slow light propagation can be achieved by controlling the driving amplitudes and phase of the phonon pump. Further, the second-order sideband (SOS) generation is also demonstrated in the system, and it is found that the efficiency of the SOS generation can be significantly enhanced with manipulating the phonon pump in the resonance regime with numerical simulations. More interestingly, the SOS generation is also sensitive to the detuning (the off-resonance regime), and a robust SOS can be induced and the efficiency of the SOS generation even presents mode splitting which is similar to the linear OMIT. These results lead to good tunability of SOS generation and may find applications in manipulation of light propagation.

在带声子泵的光机械系统中，可调节为从快到慢的光和二阶边带生成

摘要

我们从理论上证明了光机械诱导的透明性（OMIT）及其相关的相干光学传播特性，例如由弱相干声子泵驱动的腔体光机械系统中的快光和慢光效应，适用于合适的参数和失谐机制。探头的透射光谱在不同的失谐状态下经历不同的过程，并且通过控制声子泵的驱动幅度和相位，可以实现表明可调谐和可控制的快慢传播的数值模拟。此外，在系统中还演示了二阶边带（SOS）生成，并且发现通过在数值模拟中在共振状态下操纵声子泵，可以显着提高SOS生成的效率。更有趣的是 SOS代也对失谐（失谐状态）敏感，并且可以感应出健壮的SOS，并且SOS代的效率甚至呈现出类似于线性OMIT的模式分裂。这些结果导致了SOS生成的良好可调性，并可能在光传播的操纵中找到应用。
