Abstract: A method and apparatus for mass production of AR diffractive waveguides. Low-cost mass production of large-area AR diffractive waveguides (slanted surface-relief gratings) of any shape. Uses two-photon polymerization micro-nano 3D printing to realize manufacturing of slanted grating large-area masters of any shape (thereby solving the problem about manufacturing of slanted grating masters of any shape on the one hand, realizing direct manufacturing of large-size wafer-level masters on the other hand, and also having the advantages of low manufacturing cost and high production efficiency). Composite nanoimprint lithography technology is employed (in combination with the peculiar imprint technique and the composite soft mold suitable for slanted gratings) to solve the problem that a large-slanting-angle large-slot-depth slanted grating cannot be demolded and thus cannot be manufactured, and realize the manufacturing of the slanted grating without constraints (geometric shape and size).
