Fig. 3 Time delay and amplitude of the signal pulse versus the position of F-P cavity. The simulation parameters, except for z, are the same as those of fig. 2. The time delay and the amplitude of the signal pulse can be tuned by scanning the position of the cavity, thereby the light intensity in the cavity, with only nonlinear medium (red markers, n2=5e-8 m2/W), but not linear medium (blue markers, n2=0) filled. In addition, we can not observe obvious time delay when the relatively weak laser pulse pass through a free nonlinear medium, either. These phenomena can be ascribe to the combination of the photonic structure resonance and the transverse phase modulation effect.

Fig. 2 reference and signal pulses. Iin the maximum light intensity on axis at focus point is set to be 20 W/m2. The position of the cavity z=0, in other words, the cavity was put at the focal point of the laser beam. The amplitude transmittance T of the cavity mirror is 0.1. Other parameters are listed in table 1. It is clearly seen that the signal pulse (red curve) was delayed.
