We theoretically study the optomechanically induced transparency (OMIT) and absorption (OMIA) phenomena in a single microcavity optomechanical system, assisted by an indirectly coupled auxiliary cavity mode. We show that the interference effect between the two optical modes plays an important role and can be used to control the multiple-pathway induced destructive or constructive interference effect. The three-pathway interference could induce an absorption dip within the transparent window in the red sideband driving regime, while we can switch back and forth between OMIT and OMIA with the four-pathway interference. The conversion between the transparency peak and absorption dip can be achieved by tuning the relative amplitude and phase of the multiple light paths interference. Our system proposes a new platform to realize multiple pathways induced transparency and absorption in a single microcavity and a feasible way for realizing all-optical information processing.
我们从理论上研究了在单个微腔光机械系统中，由间接耦合的辅助腔模辅助的光机械诱导透明（OMIT）和吸收（OMIA）现象。我们表明，两种光学模式之间的干涉效应起着重要作用，可用于控制多路径诱导的相消或相长干涉效应。在红边带驱动 regime 中，三路径干涉可在透明窗口内诱导吸收凹陷，而我们可以通过四路径干涉在 OMIT 和 OMIA 之间来回切换。通过调整多光路干涉的相对幅度和相位，可以实现透明峰和吸收凹陷之间的转换。我们的系统提出了一个在单个微腔中实现多路径诱导透明和吸收的新平台，以及一种实现全光信息处理的可行方法。
