The application of reflected optical difference system in surface crack of aluminum detection is also discussed. By analyzing the experimental data, we found that the reflected pulsed wave techniques could be used to measure the position of crack precisely and depth imprecisely. Transmitted wave contain much size information of the crack, despite without position information. The spectrum of transmitted is sensitive to the depth of crack. The deeper the crack is, the narrower the spectrum bandwidth is.

Photonic quantum-well structures can be constructed by stacking 3 photonic crystals with the same photonic band gap and different defect modes. On condition that the defect mode of the PC in the well region is located into nontransmission frequency ranges of the PCs in the barrier regions, the confined photonic state appears and can completely transmit through the structure by tunneling. However, its transmission will be strongly prohibited due to vanishing of the photonic QW induced by shifting the defect mode frequency of either of the PCs in the surrounded regions to that of the middle PC.
把三块各带有一个缺陷的光子晶体结合起来,如果中央晶体的缺陷模处在两侧晶体的禁带中,缺陷模内的光波会受到两侧晶体的阻碍并被局域在中央晶体内,形成量子阱结构;若一侧晶体的缺陷模被移动到中央晶体缺陷模处,则只有一侧晶体阻碍在中央晶体缺陷模内传播的光波,量子阱效应完全消失,光的传输受到最大程度的阻碍。
