“…Each of the cavity lengths L i = 35 mm, (i = 1, 4), the effective pump laser detuning ∆ = Ω = 2π × 10 7 Hz, the cavity decay rate κ = 2π × 10 6 Hz, mechanical damping rate of each mirror γ mi = 2π × 10 4 Hz (i = 1, 2), mass of each mirror m i = 14.5g, (i = 1, 2), wavelength of pump laser λ = 1064 nm and pump power P pu = 10 µW respectively. It is to be noted that the parameters used in this study have been obtained from a careful survey of existing literature on macroscopic hybrid optomechanical systems [43][44][45][46][47][48][49][50][51][52]. Due to the macroscopic nature of the parameters of the four-mirror setup, the optomechanical coupling is very weak to show any observable optomechanical effects such as the optomechanically induced transparency, the Fano resonances which were earlier reported in microscopic cavities [34,41].…”

We demonstrate coherent control of optomechanically induced transparency and Fano resonances in a four mirror macroscopic optomechanical cavity, with two movable mirrors, each driven by an external mechanical pump. The variable control of the amplitude and phase of the coherent mechanical pumps provides a means of tuning the shape and nature of the Fano profiles. Further, our scheme shows the occurrence of tunable optomechanical features, even at very low mechanical driving field amplitudes, in macroscopic optomechanical cavities.

“…The performances of OMIT and OMIA processes are mainly described by the optical delay and transmission, which directly determine the storage time of information and the transfer efficiency of information, respectively. In recent years, the follow-up developments of OMIT and OMIA have been demonstrated in many schemes, such as multicavity OMIT [37,[51][52][53][54], hybrid OMIT [55,56], the two-phonon OMIT [57,58], OMIA in quadratically coupled optomechanical system [39], OMIA of atom-assisted cavity optomechanical system [40], optical amplification phenomenon in the system with mechanical gain [59], etc. Furthermore, the miscellaneous applications of OMIT has attracted a lot of attention, for instance, the fast-slow light [37,[60][61][62], the storage of light [61,63], the ultrasensitive measurements [64,65], etc.…”

We investigate the optical amplification of the output field and fast-slow light effect in a three-mode cavity optomechanical system without rotating wave approximation and discuss two ways of realizing the optical amplification effect. Resorting to the Coulomb coupling between the nanomechanical resonators, the asymmetric double optomechanically induced amplification effect can be achieved by utilizing the counterrotating term. Moreover, we find a remarkable optical amplification effect and observe the prominent fast-slow light effect at the singular point since the introduction of mechanical gain. Meanwhile, the transmission rate of the output field is increased by four orders of magnitude and the group delay time can reach in the order of 105μs. Our work is of great significance for the potential applications of optomechanically induced amplification in quantum information processing and quantum precision measurement.

“…Introducing additional components into the optomechanical system can provide new handle to control the optomechanical effects [31][32][33][34][35][36][37]. Recently solid state based analog of optomechanics has also been developing rapidly [38][39][40][41].…”

We theoretically investigate optical bistability, mechanically induced absorption (MIA) and Fano resonance of a hybrid system comprising of a single quantum dot (QD) embedded in a solid state microcavity interacting with the quantized cavity mode and the deformation potential associated with the lattice vibration. We find that the bistability can be tuned by the QD-cavity mode coupling. We further show that the normalized power transmission displays anomalous dispersion indicating that the system can be used to generate slow light.We also demonstrate the possibility of using the system as all optomechanical Kerr switch.
