Fig. 3: Numerical solutions to the phonon-cavity system operating in linear and nonlinear regimes.
From: Nonlinearity-mediated digitization and amplification in electromechanical phonon-cavity systems
All results are presented in 2D color plots. a, b Calculated response of the ω1 mode in linear regime with pumping frequency ωp near the (a) red sideband ωred and b blue sideband ωblue of the phonon-cavity. c, d Nonlinear response of the ω1 mode with an upward frequency sweep, with pump frequency ωp near the red sideband ωred (c) and blue sideband ωblue (d), respectively. e, f Nonlinear response of the ω1 mode with a downward frequency sweep, with pump frequency ωp near the red sideband ωred (e) and blue sideband ωblue (f), respectively, showing clear modulation of the bi-stability frequency ωb with distinct patterns. Calculation and plot details are provided in “Methods” and SI 2.3–2.4, with additional data in SI 3.1.
