In the paper, we have given the quantum transmissivity, probability density and probability current density of photon in one-dimensional photonic crystals (AB) N with the quantum theory approach. We find the quantum transmissivity is identical to the classical transmissivity. When the incident angle θ and periodic number N change the probability density and probability current density are approximate periodic change, and their amplitude are increased with the incident angles θ and periodic number N increasing. Otherwise, we find when the frequency of incident photon is corresponding to transmissivity T = 1, the amplitude of the probability density is the largest. When the frequency of incident photon is corresponding to transmissivity T = 0, the amplitude of the probability density attenuate rapidly to zero, it indicates that there is the quantum tunnel effect of photon in photonic crystals.
