A λ/2 Fabry-Pérot resonator is made of two parallel mirrors and has a transmission maximum for light with a wavelength, corresponding to twice the mirror separation divided by the refraction index of the medium inside the resonator. We have investigated the resonance condition for a system of three parallel mirrors, separated by half an optical wavelength, while one outer mirror can be moved. For on axis illumination of the coupled resonators with white light, anticrossing of the wavelengths of the transmission maximum can be observed for the detuning of the adjustable resonator over the length of the fixed resonator. The occurrence of the anticrossing behavior can be adjusted when changing the thickness and therefore the reflectivity of the central silver mirror. With this experiment, we can model strong coupling with different coupling strengths.
