Abstract
We report a facile, high efficiency fabrication method for subwavelength silver gratings via direct laser writing (DLW), achieving a printing speed of 18〖 mm〗^2/h. Combined with the Moiré interferometry technique, the printed gratings can be used to measure small transverse displacement with sub-micrometer accuracy.
