摘要
针对衍射光栅分束器,本文提出一种基于平面-浮雕面形调制型光栅实现分束器设计的方法。该方法根据光线追迹原理设计获得光栅相位和面形多项式函数通式,采用遗传算法优化面形多项式函数系数,分别设计了分束比为1:2×2、1:3×3、1:4×4的光栅分束器件;其衍射效率分别为81.83%、81.11%和74.01%;三个器件的光强均匀性分别达到0.02394、0.1838和0.1912,并用Matlab进行了仿真。仿真结果表明,该方法对分束器件设计具有一定的普遍适应性。
Abstract
A method is proposed for designing the grating splitter with plane-surface-relief. Ray tracing theory is used to obtain phase and universal polynomial function of grating,and the coefficient of the polynomial function is optimized by genetic algorithm. Several grating splitters with ratio 1:2×2,1:3×3,1:4×4 and diffraction efficiency 81.83%,81.11% and 74.01%respectively are designed based on the method. The simulation made by Matlab software shows that the intensity uniformities of the three gratings designed through the method achieve 0.023 94,0.183 8 and 0.191 2 respectively,which indicates that the method has universal compatibility for designing the diffraction optics components.
