What is it about?

Polarization effects in laser 3D nanolithography are employed to fine-tune the feature sizes in the structuring of photoresist. The vectorial Debye theory is used for modelling and a variation of up to ≈20% in the line width of SZ2080 is shown experimentally for the identical axial extent. This proves polarization to be a variable parameter for voxel-aspect ratio control.

3D Polymerization via Polarization Control on Nanoscale

Perspectives

The ascribed findings demonstrate that beam polarization can be used practically as the voxel’s aspect ratio tuning parameter, and should be taken into account for precise 3D fabrication of nanostructures such as PhCs and microoptical components, yet per- haps can be disregarded for some bulkier objects or larger-scale scaffolding structures of >1 µm single-feature dimensions. The effects considered are expected to be of even greater importance in mass-transport-based laser-additive nanostructuring techniques, such as the selective deposition of metallic nano-particles or the preparation of conductive 3D wires.
