Abstract

Abstract We investigate the physical properties of multiple optomechanically induced transparency in a system. The system consists of two charged mechanical resonators and an optical cavity. An optical parametric amplifier (OPA) and a two-level atom ensemble are filled into the optical cavity. Some physical phenomena appear in the system driven by the probe field and the pump field. The width of transparent windows can be manipulated by the coupling strengths of the system. Specifically, the width of the transparency window increases with an increase in the parametric gain of the optical parametric amplifier (OPA). Furthermore, the number of transparent windows and the location of transparent points are also affected by the system parameters. The presence of two-level atomic ensemble causes the double transparent windows to be split three transparent windows. The Coulomb coupling between the two charged mechanical resonators causes the transparent points to move. Our approach provides a great flexibility for manipulating multiple induced transparency. It is helpful to study the quantum properties of nonlinear optical systems.

Optomechanically induced transparency in a multi-cavity system subjected to two-level atomic ensemble interference

Gongtao Yu, Guixia Pan

Abstract We investigate a hybrid multi-cavity optomechanical system with interference from a two-level atomic ensemble. The system is composed of three optical cavities and two nanomechanical resonators. A two-level atomic ensemble is filled into the middle optical cavity. The optical cavity located in the middle has two interaction forces with the two outermost optical cavities. What is more, the system also includes various types of interaction relations, which are the couplings of optical cavities with mechanical resonators and the coupling of optical cavity with two-level atomic ensemble. In order to study the optical response of optomechanically induced transparency, we modulate the interaction intensity within the system to obtain different eletromagnetic induced transparent phenomena. It has been found that under the influence of different parameters, the number of transparent windows and the width of transparent windows increase with an increase in the coupling of the optical cavities with atomic ensemble. In addition, as the system parameters change, the transparency points also move. The position of the two outermost transparent points becomes farther apart when the coupling of optical cavity with mechanical resonators increases. Our approach provides a great flexibility for controlling electromagnetically induced transparency. It will have the great potential applications for quantum information processing.

Enhanced multicolor optomechanically induced transparency in electro-optical hybrid system

Guixia Pan, Ruijie Xiao, Chengbo Zhai

Abstract We investigate the tunable multicolor optomechanically induced transparency through electro-optical hybrid system. The system consists an optical cavity fulled with three-level atomic ensemble and two charged mechanical oscillators coupled via Coulomb interaction. Under different coupling strengths, the system can exhibit the phenomena of optomechanical induced transparency increase. Specifically, the number of the transparency windows increases with the presence of charged mechanical resonators and atoms. Furthermore, the induced transparency phenomena are strongly manipulated by the coupling strength between the optical mode and the mechanical mode, or between the optical mode and the atoms and the Rabi frequency, or between the Coulomb coupling between the two charged mechanical modes. It is found that the larger coupling strength between the cavity field and the atoms and the mechanical oscillator, the wider transparent windows. Our approach is feasible for storage of light and has potential applications in quantum information processing.

Multiple optomechanically induced transparency in the hybrid optomechanical system with the two-level and three-level atomic ensembles

Abstract We investigate the optomechanically induced transparency in a hybrid optomechanical system, which consists of two optical cavities and a mechanical resonator. The two-level and three-level atomic ensembles are trapped in the two optical cavities, respectively. We focus on the changes in the number and width of transparency windows and the position of transparent points under different conditions influenced by various interactions. Five transparency windows can be observed when all the interactions are on. The introduction of two-level and three-level atomic ensembles can increase the number of transparency windows and also provide better flexibility for controlling the width of the transparency windows. Specifically, the two-level and three-level atomic ensembles contribute one and two transparency windows, respectively. The stronger coupling results in the larger transparency windows and movement of the transparent points. Moreover, we also study the slow/fast light phenomenon through the variation of phase and group delay. These results may contribute to the research of nonlinear optics and have potential applications in optical signal processing and communication.

Multiple optomechanically induced transparency and slow/fast light in a multicavity system with two-level atoms

Tianyu Zhou, Guixia Pan

Abstract We investigate the phenomenon of optomechanically induced transparency assisted by a hybrid two-cavity optomechanical system. The system consists of two optical cavities and four mechanical resonators, and each optical cavity is filled with two-level atomic ensembles. Our study demonstrates that the characteristics of optomechanically induced transparency vary with different coupling parameters. Specifically, the number of transparent windows increases with the introduction of atomic ensembles and Coulomb interaction. Furthermore, the positions of the transparent points can be manipulated by the coupling parameters. It is found that increasing the Coulomb coupling between mechanical oscillators shifts the transparent points further apart. Furthermore, we also explore the slow/fast light effect by analyzing the phase and group delay of the probe field. Our approach enables the control of multiple optomechanically induced transparency and provides potential applications in quantum information processing.

Tunable multicolor optomechanically induced transparency and slow-fast light in hybrid electro-optomechanical system

Ruijie Xiao, Guixia Pan, Ye Liu

Abstract We investigate the tunable multicolor optomechanically induced transparency and the effect of slow/fast light in a hybrid electro-optomechanical system, in which a degenerate optical parametric amplifier (OPA) and a Λ − type three-level atomic ensemble are placed in a optical cavity with two oscillator modes. The system is driven by a strong pump field and a weak probe field, respectively. Multicolor transparency windows appear in the output field under the atom-photon-OPA-phonon-phonon coherent interaction. And the position and width of the transparent port of the output field can be manipulated by properly modifying the different parameters of the subsystem. We also research the slow/fast light effect related to phase and group delay in the probe field. Our proposal provides a great flexibility for phonon storage and has some potential applications in quantum information processing.

Normal‐Mode Splitting and Optomechanically Induced Absorption, Amplification, and Transparency in a Hybrid Optomechanical System

Tie Wang, Ming‐Hua Zheng, Cheng‐Hua Bai +4 more

Abstract The various properties of the output spectrum for a probe field in a hybrid optomechanical system that is composed of two cavities, each containing an atomic ensemble and a mechanical resonator, is analyzed. Also, the normal‐mode splitting behaviors induced by the interactions between subsystems in detail are discussed and their respective effects are clarified. The interpretations for the linear variation of the separation between two absorption peaks is given out. In the available parameter regime, three tunnel coupling critical points, which describe the transition behaviors between absorption and amplification, are determined. Based on the first critical point, the influence of the two‐level atomic ensemble on absorption (amplification) effect is studied. The effect of the two‐level atomic ensemble not only splits the absorption peak (amplification dip), but also realizes the enhancement of the absorption (amplification) effect and the transformation between absorption and amplification effects. Meanwhile, the one‐to‐one correspondence location relations between the transparency dip and absorption peak for the double optomechanically induced transparency‐like and optomechanically induced absorption‐like, respectively, are also investigated. With a multi‐level atomic ensemble, the multi‐transparency (absorption) effect is realized readily. These rich spectrum properties of the probe field may benefit forward achieving of the optical switch in experiment and possible applications in coherent control of light pulses.
