Subwavelength Microstructures Fabrication by Self-Organization Processes in Photopolymerizable Nanocomposite

الملخص EN

This paper describes our research results on nanometers sizes subwavelength nanostructure fabrication by UV curing of special nanocomposite material with self-organization and light self-focusing effects.

For this purpose, special UV curable nanocomposite material with a set of effects was developing: light self-focusing in the photopolymer with positive refractive index change, self-organization based on photo-induced nanoparticles transportation, and oxygen-based polymerization threshold.

Both holographic and projection lithography writing methods application for microstructure making shows geometrical optical laws perturbation as result of nanocomposite self-organization effects with formation of nanometers-sized high-aspect-ratio structures.

Obtained results will be useful for diffraction limit overcoming in projection lithography as well as for deep lithography technique.
