title: Band-edge oscillations of the diffraction spectrum of a volume hologram investigated by the air-doping model.
abstract: Oscillation exists at the high-frequency band edge in the diffraction spectrum of a volume hologram. An air-doping model of a volume hologram is proposed to explain the phenomenon. The numerical results show good agreement with the experimental results, which cannot be explained by the conventional models. The results show that the position of air impurity is the key factor to control the number and width of the oscillations. The present work gives a new approach to generate and control the defect mode in a holographic photonic crystal.
