  • 3D PRINT MICROSTRUCTURES FOR AR WAVEGUIDE PACKAGING AND PROTECTION
    Publication number: 20240142694
    Abstract: Techniques, systems, and assemblies are presented relating to micro spacers positioned between optical substrates. In some embodiments, a stacked optical assembly comprises a first optical substrate having a first index of refraction greater than 1.4, a second optical substrate having a second index of refraction greater than 1.4 and disposed in a stacked position relative to the first optical substrate, and a plurality of micro spacers positioned between the first optical substrate and the second optical substrate. The plurality of micro spacers may maintain a gap having a gap height between the first optical substrate and the second optical substrate. The plurality of micro spacers may be fixedly attached to (a) the first optical substrate, (b) the second optical substrate, or (c) both the first optical substrate and the second optical substrate.
