| 中文摘要 | beam splitting of low-contrast rectangular gratings under second bragg angle incidence is studied. the grating period is between lambda and 2 lambda. the diffraction behaviors of the three transmitted propagating orders are illustrated by analyzing the first three propagating grating modes. from a simplified modal approach, the design conditions of gratings as a high-efficiency element with most of its energy concentrated in the -2nd transmitted order (similar to 90%) and of gratings as a 1 x 2 beam splitter with a total efficiency over 90% are derived. the grating parameters for achieving exactly the splitting pattern by use of rigorous coupled-wave analysis verified the design method. a 1 x 3 beam splitter is also demonstrated. moreover, the polarization-dependent diffraction behaviors are investigated, which suggest the possibility of designing polarization-selective elements under such a configuration. the proposed concept of using the second bragg angle should be helpful for developing new grating-based devices.
