Abstract

Based on medium-tuned optical field enhancement effect around a self-assembled particle-lens array (PLA) irradiated with a femtosecond (fs) laser source, we demonstrated that high-precision periodical array of micro/nano-structures can be readily fabricated on glass surface or inside glass in large areas in parallel without any cracks or debris. The technique has potential for rapid fabrication of three-dimensional structures in multiple layers inside glass.

Cross-sectional view of normalized local field distribution (|E|2) underneath a hexagonal array of 5.0 µm particles deposited on Quartz substrate (a) in air and (b) immersed in water. The incident beam has a wavelength of 800 nm and is polarized along horizontal-direction. The refractive index of quartz and spheres are same as 1.45332, and 1.326 for water. (c) the electric field on substrate surface just under the particles.
