| Summary: | In this study, SiN-based gratings with various radius of curvature (<italic>r</italic>) are designed and fabricated for the optical addressing of trapped Sr<sup>+</sup> ion. The beam width of the light coupled out from the gratings is investigated using a self-developed Python-based data analysis technique. It is found that the <italic>r</italic> values have insignificant influence on the beam width along <italic>x</italic>-axis; whereas the beam waist along <italic>y</italic>-axis reduces from 13.96 to 12.3 μm as <italic>r</italic> increases from 15 to 20 μm, then increases gradually to 20.51 μm as the <italic>r</italic> value further increases to 60 μm. The obtained results can provide a versatile solution on the optical addressing of trapped Sr<sup>+</sup> for applications in quantum engineering. |
