Figure 5

FTIR experimental measurement of the reflected power (black lines) for the two fabricated samples, the thinner TiO₂ cavity sample (top panels) and the thicker ZnO cavity sample (bottom panels) for the two polarizations, E = \(E_x\) [(a) and (c)] and E = \(E_y\) [(b) and (d)]. The measurements are corroborated by the corresponding simulation (green and blue curves).
