The purpose of this project is to investigate the strong localization of light waves in aperiodic waveguides. In particular, we have payd attention to a role of nonlinearity to the localization of light. Followings were clarified, (i) it became clear that the strong localization of light surely occurs (ii) the nonlinearity enhances the localization. Those results were obtained via largescale computer simulations.

本计画主要研究光波在非周期波导中的强定域化现象。特别地，我们注意到非线性对光的局域化的作用。阐明了：（i）很明显，光的强局域化一定会发生;（ii）非线性增强了局域化。这些结果是通过大规模计算机模拟获得的。
