Optomechanically induced sum sideband generation

Abstract

Sum sideband generation in a generic optomechanical system is discussed in the parameter configuration of optomechanically induced transparency. The nonlinear terms of the optomechanical dynamics are taken account and the features of the sum sideband generation are identified based on the analytical treatment. The nonlinear optomechanical interactions between cavity fields and the mechanical oscillation, which emerging as a new frontier in cavity optomechanics, are responsible for the generation of the frequency components at the sum sideband. We analyze in detail the influences of some parameters, including the pump power of the control field and the frequencies of the probe fields, on the sum sideband generation. The results clearly indicate that sum sideband generation can be significantly enhanced via achieving the matching conditions. The effect of sum sideband generation may be accessible in experiments and have potential application for achieving high precision measurement and on-chip manipulation of light propagation.

Enhancement of optomechanically induced sum sidebands using parametric interactions

“…Here, we only consider sum sidebands, then the efficiency of the upper and lower sum sideband can be define as η + s = | − √ η c κa + s /ǫ 1 | and η − s = | − √ η c κa − s /ǫ 1 | respectively, which are the ratio between amplitudes of the sum sideband and the first probe field, and thus dimensionless. In the previous work [37], it is shown that the efficiencies of sum sideband generation exhibit peak structure for some specific values of δ 1 and δ 2 . The specific values of δ 1 (δ 2 ) corresponding to these peaks are called as the matching conditions.…”

“…While such linearized dynamics can explain many phenomena arise in cavity optomechanics, the nonlinear terms −iGδxδa and −hGδa * δa must be taken into account for the discussion of sum sideband generation, which is out of the frequency space of linearized dynamics. To calculate the amplitudes of the sum sidebands, we assume that the fluctuation terms δa and δx have the following forms [10,37]:…”

“…This emerging subject leads to a variety of high-order OMIT effects due to the intrinsic nonlinear optomechanical interactions [31,32], such as photon-phonon polariton pairs [33] and sideband generations [27,34,35]. In particular, OMIT with multiple probe fields driven has also been explored [36,37]. * E-mail: liwenan@126.com, liwa@gzhu.edu.cn Generation of spectral components at sum (or difference) sideband are demonstrated analytically, which may have great potential in the precise measurement of parameters and phonon number of optomechanical systems [38][39][40][41].…”

“…Nonlinear features of optomechanical systems with multiple probe field driven have been discussed recently [23], and spectral signals at difference sideband has been demonstrated analytically which provides an effective way for light manipulation and precision measurement in a solid-state architecture [24].

Dynamic control of coherent pulses via destructive interference in graphene under Landau quantization

“…Although a lots of quantum optical effects have been observed in the past decades and within different physics systems, there is renewed interest in such time-dependent dynamic effects which may include solitons 16–20 , creation of short pulses 21–25 , and multiwave mixing processes in the ultraslow propagation regime 26–28 , etc. 29–31 . In particular, time-dependent coherent control of the optical response of certain media that exhibit electromagnetic induced transparency (EIT) 13–15 has also triggered a flurry of interest mainly due to its potential applications in integrated optics and quantum information science.…”
