We suggest a flexible control of the diffraction grating by considering an optomechanical cavity system. The cavity is driven by an external control standing wave and realizes the characteristics of the diffraction grating when the light beam interacts with the cavity, a phenomenon which we name optomechanically induced grating (OMIG). A standing wave consists of nodes and antinodes that lead to gratings or slits in the cavity system. The reflected probe field from a moving mirror is diffracted through a standing wave and comes out through a partially reflected mirror. Effective control of the diffraction grating is achieved with the manipulation of the optomechanical strength g_mc ( the so-called mirror-light interaction strength). Fascinatingly, the first, second, and third-order diffraction gratings can be easily achieved via the mirror-light interaction strength g_mc. The diffraction grating is found to be influenced by the cavity decay rate. For small values of the decay rate, the diffraction grating becomes maximum and vice versa. The results of our model can bring potential applications in optomechanical systems.

光机感应光栅

我们建议通过考虑光机械腔系统来灵活控制衍射光栅。腔体由外部控制驻波驱动，当光束与腔体相互作用时实现衍射光栅的特性，我们将这种现象称为光机械感应光栅（OMIG）。驻波由波节和波腹组成，这些波节和波腹通向腔系统中的光栅或狭缝。来自移动镜的反射探测场通过驻波衍射，并通过部分反射镜射出。通过操纵光机械强度g _mc实现对衍射光栅的有效控制（所谓的镜光相互作用强度）。令人着迷的是，一阶、二阶和三阶衍射光栅可以通过镜光相互作用强度g _mc轻松实现。发现衍射光栅受腔衰减率的影响。对于较小的衰减率值，衍射光栅变为最大值，反之亦然。我们模型的结果可以在光机系统中带来潜在的应用。
