Abstract: We gave the quantum transmissivity of onedimensional photonic crystals with nonvertical incidence, and studied the effects of the defect layer, incident angle, thickness of medium layer and refractive index of medium layer on the transmission characteristics of onedimensional photonic crystals, respectively, and compared their results with the classical method results. The results show that when the light enters onedimensional photonic crystals at a certain angle, the quantum method results has quantum effect.

Key words: nonvertical incidence, photonic crystal, quantum method
