Figure 1 Schematic diagram of a three-dimensional integrated multichannel waveguide grating filter: (a) 1:1 planar beam splitter, (b) 1:1 three-dimensional beam splitter, (c) waveguide gratings ...
Researchers developed a new optimized printing approach that could enable super-resolution 3D direct laser writing (DLW) of microlenses, photonics crystals, micro-optical devices, metamaterials and ...
Researchers showed that their optimized direct laser writing approach could create high-resolution line gratings on a glass substrate. These SEM images show line gratings the researchers created using ...
