Figure 36: Plots of the locally-optimized SQL beating factor ξ(Ω ) (418View Equation) of the interferometer with cross-correlated noises for the “bad cavity” case Ω0 ≪ γ, for several different values of the optimization frequency Ω0 within the range √ --- 0.1 × Ωq ≤ Ω0 ≤ 10 × Ωq. Thick solid lines: the common envelopes of these plots; see Eq. (420View Equation). Left column: ηd = 1; right column: ηd = 0.95. Top row: no squeezing, r = 0; bottom row: 10 dB squeezing, e2r = 10.
