|
Abstract:
利用特征矩阵方法，研究基于Fabry-Peror腔共振原理设计膜系的吸收增强效应。研究发现这种结构可以实现特定波段激光的吸收增强，通过调整膜系结构、吸收介质的位置等因素实现较宽光谱的高吸收率，结果表明吸收介质对应波长的吸收率提高了一个数量级。
By using the characteristic matrix method, the enhanced absorption effects of optics multilayer, which was designed based on Fabry-Peror cavity resonance, were studied, and the investigation showed that this multilayer structure could realize the absorption enhancement in the particular band. Meanwhile, the absorption spectrum width could be broadened by modifying the film structure and the location of the absorbing medium. The results showed that the absorption rate was raised an order of magnitude in the particular band.？
