本文利用投影法提出了一种啁啾拟周期结构。这种新型结构结合了啁啾和准周期结构的优点，可用于多次准相位匹配和多带宽控制。二次谐波产生性能的数值模拟与结构的傅立叶谱吻合较好。
We propose in this paper a chirped-quasi-periodic structure using the projection method. This type of new structure combines the advantages of chirped and quasi-periodic structures, and can be used for both multiple quasi-phase-matching and multiple bandwidths control. Numerical simulation of second-harmonic generation performance is in good agreement with the Fourier spectrum of the structure.
