    Sketch of the system.
    Fig. 1. Sketch of the system.
    Intracavity steady-state mean photon number |as|2 varies with (a) the sphere–mirror separation and (b) the power of the controlling field. The parameters used are m=145 ng, ωm=2π×947 kHz, Γm=2π×141 Hz, R=150 nm, κ=2π×215 Hz, ωl=2 πc/λ, λ=1064 nm, g=2π×70 GHz/μm, and Δl=ωm. In addition, (a) Pl=10 μW and (b) d=2 nm.

The parameters used are m=145ng, ωm=2π×947kHz, Γm=2π×141Hz, R=150nm, κ=2π×215Hz, ωl=2πc/λ, λ=1064nm, g=2π×70GHz/μm, and Δl=ωm. In addition, (a) Pl=10μW and (b) d=2nm.
    Output spectra for different values of the sphere–mirror separation d: (a) d=∞, (b) d=2 nm, (c) d=1.8 nm, and (d) d=1.5 nm. We use εp=εl/2. The power of the controlling field is Pl=30 μW. The other parameters are the same as in Fig. 2.
