What we believe to be a new method for designing multilayer diffractive optical elements (MLDOEs) for wideband with consideration of polychromatic integral diffraction efficiency (PIDE) is presented. The benefit of this method is that the maximum PIDE over the entire waveband for MLDOEs can be obtained. The design process and simulation of the MLDOEs with regard to an example for visible waveband are described, and the comparison of diffraction efficiencies of the MLDOEs for different choices of design wavelengths with different methods is given.
我们提出了一种新的设计方法，用于设计考虑多色积分衍射效率 (PIDE) 的宽带多层衍射光学元件 (MLDOE)。这种方法的优点是可以获得 MLDOE 在整个波段的最大 PIDE。本文描述了 MLDOE 的设计过程和可见光波段的模拟，并给出了不同设计波长和不同方法下 MLDOE 的衍射效率比较。
