Reflectivity spectra for different pump–probe time delays: curve (a) obtained at corresponds to the linear reflectivity; (b) ; (c) ; (d) ; (e) ; (f) ; (g) ; (h) ; (i) , and (j) . The pump and probe intensities are 1.6 and , respectively.
Measured blueshift of the resonance as a function of the pump–probe time delay for three different pump intensities: (triangle dots), (circular dots), (square dots). The inset represents shift decay time as a function of the pump intensity.
Reflectivity spectra around the PC resonance wavelength for two different pump powers: for curve (b) and for curve (a). Dashed line represents the linear reflectivity. All spectra are normalized to the maximum of the linear reflectivity.
Measure of the differential reflectivity as function of the pump–probe delay at: (a) (triangular dots) and (circular dots); (b) (triangular dots) and (circular dots).
