“…As a result, the probe field cannot exist in the cavity, and the cavity then becomes transparent. A system can also be designed such that a constructive interference take place that leads to optomechanically induced absorption (OMIA) [77,78]. In this section, we analyze the existence of OMIA in terms of the left-hand or right-hand output probe fields.…”

We theoretically investigate the optical response in a hybrid quantum optomechanical system consisting of two optically coupled micro-cavities in which a twolevel system (qubit) is embedded on a movable membrane. The qubit can either be a defect which interacts with the mechanical oscillator via the linear Jaynes-Cummings interaction or a superconducting charge qubit coupled with the mechanical mode via nonlinear interaction. We find that coherent perfect transmission (CPT), coherent perfect synthesis (CPS) and optomechanically induced absorption (OMIA) can be generated by suitably adjusting the system parameters. We find that the qubit and

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.

“…optical mode and mechanical degrees of freedom. Since the optomechanical coupling is intrinsically nonlinear, cavity optomechanical systems display various types of nonlinear behavior like bistability/multistability [1][2][3][4], optical field squeezing [5,6], optomechanically induced transparency (OMIT) [7][8][9], normal mode splitting [10][11][12][13], quantum state transfer [14,15], quantum entanglement [16][17][18] and many more. These quantum phenomena provided by cavity optomechanical system finds application in quantum information processing and precision measurement [19], optical data storage [20], optical memories [21], quantum metrology [22], gravitational wave detection [23,24], and more.…”

We theoretically investigate the optomechanical interaction between an optical ﬁeld and a mechanical mode mediated by a Kerr nonlinear medium inside an optical cavity and simultaneously driven by an external amplitude-modulated pump ﬁeld and a probe ﬁeld. We show that switching between bistability and multistability is inﬂuenced by the rocking parameter and Kerr nonlinearity. Further, we study the quantum ﬂuctuation dynamics of the system, which shows the quantum coherence and interference eﬀects resulting in the transmission of the probe ﬁeld from opacity to ampliﬁcation. We also ﬁnd that the rocking parameter, Kerr nonlinearity, and the optomechanical coupling inﬂuence the transmission spectrum. In addition, we also show that the rocking parameter signiﬁcantly enhances the optomechanical coupling, which can be a new handle to control the entanglement between the optical and mechanical modes. The results show that such a hybrid optomechanical system has potential application in designing and optimizing all-optical switching and optical sensors.
