Two-color second-order sideband generation in an optomechanical system with a two-level system

Abstract

Second-order sideband generation in an optomechanical system with the coupling between a mechanical resonator and a two-level system is discussed beyond the conventional linearized description of optomechanical interactions. The features of two-color second-order sideband generation are demonstrated in this hybrid system. We discovery that the switch between one- and two-color second-order sideband generation is easily realized by shifting the detuning between the control field and the cavity field or the transition frequency of the two-level system. The efficiency of two-color second-order sideband generation increases monotonously with the control field strength. The coupling strength between the mechanical resonator and the two-level system plays a decisive role in the appearance of the two-color second-order sidebands. The two-color second-order sideband generation may provide measurement with higher precision in new degrees of freedom.

Quantum mechanical treatment of two-level atoms coupled to continuum with an ultraviolet cutoff

“…Ref. [1][2][3][4][5][6][7][8][9][10][11][12][13][14]). The approach proposed in Ref.s [15,16] presents a treatment of two-level systems in real space, while the Dicke-Hamiltonian [17] is transformed into the real space and used to predict a mirror behavior of two-level atoms for certain wavelength of light.…”

“…The foundations laid out by the existing formalism and experimental opportunities for the two-level atom and photon interactions has allowed treating complex systems (e.g. [1][2][3][4][5][6][7][8][9][10][11][12][13][14]). The approach proposed in [15,16] presents a treatment of two-level systems in real space, while the Dicke-Hamiltonian [17] is transformed into the real space and used to predict a mirror behavior of two-level atoms for certain wavelength of light.…”

Optical Response and Drift Matrix of Quadratic Optomechanical System

“…In this article we have considered the variation of transmission intensity of an optically driven quadratic optomechanical system containing two atomic levels with various parameters of the following system. Previously, the variation of optical response (optical transmission) within two sideband limits [24] of cavity detuning for a linearly coupled optomechanical system has been discussed analytically as well as numerically in Ref. [25] which we have reproduced on the way for quadratic optomechanical system.…”

Ideal optomechanically induced transparency generation in a cavity optoelectromechanical system*

“…[5]. Subsequently, many significant new phenomena have been achieved base on OMIT, such as reversed OMIT, [17,18] nonlinear OMIT, [19] vector OMIT, [20] multiple OMIT, [15,21] higher-order OMIT, [22] and nonreciprocal OMIT. [23] These phenomena make cavity optomechanical system a powerful platform to realize light storage and delay [24,25] on account of the abnormal dispersion accompanied with a small width of the transparency window.…”
