“…It is of great interest to investigate the significant phenomena in the optomechanical system. Therefore, many interesting phenomena have been researched in the optomechanical system such as OMIT [1, 2, 24, 25], optical bistability and multistability [9, 20, 26–28], four‐wave mixing [7, 27, 29, 30], sideband effect [31–35], entanglement [36–40], squeezing [41–45], ground‐state cooling [46–49], photon blockade [50], etc.…”

We theoretically investigated the photothermally and optomechanically induced transparency (PTIT and OMIT) in an optomechanical system filled with quantum dots (QDs). In our proposed system, the right mechanical resonator couples with the optical cavity via radiation pressure, and the left mechanical resonator couples with the optical cavity through the photothermal effects. The system is driven by a strong pump field and a weak probe field. It is shown that double transparency windows can be observed due to PTIT and OMIT. When considering the Jaynes‐Cummings coupling between the QDs and the optical cavity, three transparency windows are observed. We also show that the PTIT can be adjusted by the OMIT and the QDs in the optical cavity. What is more, the coupling strength and the frequency detuning can be used effectively to change the system absorption and dispersion in the PITT transparency window. This indicates that the group delay of the probe light can also be manipulated by the system parameters. The obtained results may be applied in the optical communication such as optical buffer, and so forth.

“…With the development of nanotechnology, various physical systems which can exhibit such interaction have been proposed and investigated, such as Fabry-Perot cavities [2,3], whispering-gallery microcavities [4][5][6], superconducting circuits [7,8] and membranes [9][10][11][12]. The optomechanical interaction can strongly affect the motion of mechanical oscillator and the optical properties in these systems, and then various interesting quantum phenomena can be generated, such as ground-state cooling of mechanical modes [13][14][15][16][17][18][19][20], quantum entanglement [21][22][23][24][25][26][27][28], mechanical squeezing [29], unconventional photon blockade [30], and optomechanically induced transmission and absorption [31][32][33][34][35][36][37][38][39][40][41][42].…”

Here, we study the controllable optical responses in a two-cavity optomechanical system, especially on the perfect optomechanically induced transparency (OMIT) in the model which has never been studied before. The results show that the perfect OMIT can still occur even with a large mechanical damping rate, and at the perfect transparency window the long-lived slow light can be achieved. In addition, we find that the conversion between the perfect OMIT and optomechanically induced absorption can be easily achieved just by adjusting the driving field strength of the second cavity. We believe that the results can be used to control optical transmission in modern optical networks.

“…As a crucial element for engineering the propagation of phonons, nonreciprocal phononic devices have a wide range of applications, including phonon isolation [34], one-way mechanical networks [36,65], acoustic imaging, and chiral phonon transport or cooling [19,20,66]. In particular, nonreciprocal mechanical cooling was theoretically proposed by using the relativistic Sagnac effect in a spinning COM device [67]. However, these schemes are technically challenging in experiments as they require high-speed rotation of the optical resonators while maintaining stable resonator-fiber or resonator-resonator coupling strengths [30].…”

“…Moreover, we find that the cooling efficiency is improved; that is, mechanical cooling deep into the groundstate is accessible due to the squeezing effect. Compared to the schemes based on spinning the optical resonators [67], our scheme for achieving nonreciprocal enhancement of optomechanical cooling requires only two-mode matching in one resonator, and therefore could be practical to implement in experiments. As such, we anticipate that our work could serve as a useful tool to explore controlled switching between classical and quantum states, provide a solid foundation to engineer various backscatter-immune quantum effects with diverse nonreciprocal devices, and facilitate a variety of emerging quantum technologies ranging from quantum information processing to quantum sensing.…”

We theoretically propose how to achieve nonreciprocal enhancement of mechanical cooling in a compound cavity optomechanical system composed of an optomechanical resonator and a χ(2)-nonlinear resonator. By parametric pumping the χ(2)-nonlinear resonator unidirectionally with a classical coherent field, quantum squeezing of the resonator mode emerges in one direction but not in the other, resulting in asymmetric optical detuning and a tunable chiral photon interaction between two resonators. As a result, nonreciprocal mechanical cooling is achieved. More importantly, enhanced mechanical cooling deep into the ground-state can be achieved in the selected directions due to the squeezing effect. These results provide an experimentally feasible way to realize nonreciprocal ground-state cooling of mechanical resonator, which may have a wide range of applications in quantum communication and quantum technologies.
