We investigate a double cavity optomechanical system(OMS) generating single and double Fano resonance(multi Fano). By altering a single parameter, the tunneling rate $g$ of the middle mirror, we are able to switch between single and double Fano line shapes. The first spectral line shape is stronger in the case of multi Fano than in the case of single Fano. Also the behaviour of steady state value of the displacement of the middle mirror with respect to $g$, heavily influences the behaviour of double Fano lines in our scheme. This tunability along-with using a single pump and signal/probe laser has an added advantage in situations where only low power consumption is available.

具有谐波束缚镜的新型双腔光机系统中的 Fano 轮廓

我们研究了一个双腔光机械系统 (OMS) 产生单和双 Fano 共振 (multi Fano)。通过改变单个参数，中间镜的隧道率 $g$，我们能够在单双 Fano 线形状之间切换。多法诺情况下的第一谱线形状比单法诺情况强。此外，中间镜位移的稳态值相对于 $g$ 的行为，严重影响了我们方案中双 Fano 线的行为。这种可调谐性以及使用单个泵浦和信号/探针激光器在只有低功耗可用的情况下具有额外的优势。
