Figure 2

The spectra of the output field z of the CCD driven by a coherent input field w . Each subplot shows the output power spectrum (in dB) for a different value of the voltage \(V_{\mathrm{phase}}\) that controls the phase shift ϕ induced in the feedback field u. The blue lines are data measured in the experiment and the orange lines are theoretical predictions based on the SLH model for the CCD with optimally fitted parameter values. The parameter fitting was done independently for each value of \(V_{\mathrm {phase}}\).
