We investigate the optomechanically induced transparency phenomena assisted through cavity optomechanical system. The system consists of an optical cavity system filled with the two-level atomic ensemble and driven by a weak probe laser as well as a strong coupling fields. Under different driving conditions, the system can exhibit the phenomena of optomechanical induced transparency dip. Specifically, the width of the transparency window increases with an increase in the coupling constant, while decreasing with an increase in atomic decay rate. Furthermore, the induced transparency phenomena are strongly affected by the number of atoms, coupling, and the decay rate. It is found that the larger the number of atoms, the wider the window of induced transparency, and therefore enhance the depth of transparency window. These results may have spectacular applications for slowing and on-chip storage of light pulses by the use of a micro-fabricated optomechanical array.
我们研究了通过腔光机械系统辅助的光机械诱导透明现象。该系统由一个充满二能级原子系综的光学腔系统组成,并由一个弱探测激光以及一个强耦合场驱动。在不同的驱动条件下,该系统可以表现出光机械诱导透明凹陷现象。具体而言,透明窗口的宽度随着耦合常数的增加而增加,同时随着原子衰变率的增加而减小。此外,诱导透明现象受到原子数量、耦合和衰变率的强烈影响。研究发现,原子数量越多,诱导透明窗口越宽,从而增强了透明窗口的深度。这些结果可能在利用微纳加工的光机械阵列实现光脉冲的慢化和片上存储方面有显著应用。
