摘要：
The physical origin of the ultrafast response of nonlinear photonic crystal (PC) atoms to the excitation of ultrashort pulses is investigated in detail. It is found that the dynamic shift of PC defect modes is responsible for the dramatic shortening of the photon lifetime in nonlinear PC atoms. The transmission spectra for nonlinear PC atoms that resulted from the dynamic shift are calculated and they are in good agreement with the simulation results.
