Optomechanical analog of two-color electromagnetically induced transparency: Photon transmission through an optomechanical device with a two-level system

Abstract

Some optomechanical systems can be transparent to a probe field when a strong driving field is applied. These systems can provide an optomechanical analogue of electromagnetically-induced transparency (EIT). We study the transmission of a probe field through a hybrid optomechanical system consisting of a cavity and a mechanical resonator with a two-level system (qubit). The qubit might be an intrinsic defect inside the mechanical resonator, a superconducting artificial atom, or another two-level system. The mechanical resonator is coupled to the cavity field via radiation pressure and to the qubit via the Jaynes-Cummings interaction. We find that the dressed twolevel system and mechanical phonon can form two sets of three-level systems. Thus, there are two transparency windows in the discussed system. We interpret this effect as an optomechanical analog of two-color EIT (or double-EIT). We demonstrate how to switch between one and two EIT windows by changing the transition frequency of the qubit. We show that the absorption and dispersion of the system are mainly affected by the qubit-phonon coupling strength and the transition frequency of the qubit.

Fully coupled hybrid cavity optomechanics: Quantum interferences and correlations

“…The coupling of the light field of an optomechanical cavity to a collective excitation such as a Bose-Einstein condensate [18] or a quantum well excitonic transition [19] has also been studied. More recently, the possibility to reach strong optomechanical coupling has opened the way to studies exploring hybrid systems containing a single two-level atom [20][21][22][23][24].…”

Tunable double optomechanically induced transparency in an optomechanical system

“…This brings about the following question: What would happen in an OMIT * changjianqi@gmail.com † mangfeng@wipm.ac.cn ‡ zmzhang@scnu.edu.cn with two transparency windows (i.e., double-OMIT)? To the best of our knowledge, there have been a few theoretical schemes [37][38][39] for the double-OMIT with different models, using a nonlinear crystal or a qubit in an optomechanical cavity [37,38], and using a ring cavity with two movable mirrors [39]. However, in all the schemes mentioned above, the frequency of the transparency light for the double-EIT or double-OMIT cannot be changed due to the fixed coupling for splitting the transparency windows.…”

Bistability in a hybrid optomechanical system: effect of a gain medium

“…Quantum optomechanics is a field of research in quantum optics which investigates the interaction between light and mechanical degrees of freedom [1][2][3][4][5][6][7][8][9][10][11][12][13]. In optomechanical systems, in which light pressure affects mechanical oscilla tions, notable physical phenomena has been observed, such as the cooling of mechanical oscillations [3,4,[14][15][16][17][18], photon blockade [19][20][21][22][23], single photon nonlinearity [24], optical bistability [9,11,12,[25][26][27][28][29][30] and photon-photon interactions [31].…”

“…Therefore, in these systems, optical bistability has been investigated via the study of the position of the oscil lating mirror. To take perfect control of an optomechanical system, a number of authors have proposed some systems containing different physical options, such as atomic [3,8,11,20,33,34,36] and nonlinear mediums [35][36][37][38]. Recent evidence suggests that a nonlinear medium can modify the bistability of an optomechanical system [35].…”
