中文摘要: 基于光学超晶格的二维准晶能够同时实现多个耦合参量过程,在多辐射光源产生、多色光孤子、多个纠缠光源等领域有潜在应用。本项目拟结合多重准位相匹配理论,提出一种用于实现级联非线性过程的二维准晶的设计方法,通过对新结构中波传播的理论研究,获得新的非线性效应,实现对光的位相、偏振、传输等诸多特性的控制和操纵。

英文摘要: Two-dimensional quasicrystal based on optical supperlattice can simultaneously phase-match multiple coupled parametric processes. It has potential applications in the creation of multi-wavelength laser source, multi-soliton, and quantum optics. The content of this project is: based on the theory of multiple quasi-phase matchings, we propose a new method of designing two-dimensional quasicrystal which can be used in cascaded nonlinear process. There would be new nonlinear characters in the structure and these characters are beneficial to help us to control the phase, polarization, and propagation of light.
