Fig. 1. Optomechanics in a rotating microresonator coupled to a stationary tapered fiber. The resonator contains a mechanical mode at frequency ωm, driven by a pump field at frequency ωl, and the frequency of rotation is positive (Ω>0) for the CW direction.
Fig. 2. (a, c, d) Transmission of the probe light as a function of the optical detuning Δp and (b) rotation speed |Ω|. The rotation speed is set as (a, b) 40 kHz and (c, d) 100 kHz.
Fig. 3. (a) Group delay of the probe light τg at Δp=0, as a function of the rotation speed |Ω|. (b) Enhancement factor of the group delay D as a function of the probe detuning Δp and rotation speed |Ω|.
