报道了一种新型位相型量子点阵列衍射光栅（QDADG）。与早期的振幅型QDADG [C. Wang等人，Rev. Sci.仪器。78，053503（2007）]，新的相位型QDADG将消除某些波长处的零级衍射，并抑制更高阶的衍射。本文介绍了该传感器的基本概念、制作方法、标定技术和标定结果。这种光栅可应用于分束、激光探针诊断等研究领域。
A novel phase-type quantum-dot-array diffraction grating (QDADG) is reported. In contrast to an earlier amplitude-type QDADG [C. Wang et al., Rev. Sci. Instrum. 78, 053503 (2007)], the new phase-type QDADG would remove the zeroth order diffraction at some certain wavelength, as well as suppressing the higher-order diffractions. In this paper, the basic concept, the fabrication, the calibration techniques, and the calibration results are presented. Such a grating can be applied in the research fields of beam splitting, laser probe diagnostics, and so on.
