Theoretical and experimental transfer function of the reflective mode of the Fabry-Perot interferometer. Top shows the measured and theoretical interference response of the cavity as a function of increasing phase delay (i.e. increasing fiber-cantilever separation). This fiber end has a 30% back reflection. Bottom shows the first full interference peak that occurs as peak intensity as a function of phase delay. The experimental data is plotted with the theoretical fit
