Silica Nano-Networks as Stretches on Segmented SU8 Rods for Sub-Wavelength Photonics
2011
We report an original approach based on a fluidic mechanism involving silica nano-particules that allowed us to design a elaborate set of segmented-optical structures such as arranged clusters of pillars and cross-tapered-waveguides. We show that the association of such complex segmented pre-formed structures can be specifically shaped, by way of coupling nano-fluidics and drying mechanisms. The formation of specific silica nano-patterns or organized networks of silica nano-ridges may be predictable and in perfect agreement with the theory of minimal surfaces dealt with physics of fluids. The interest of such nano-photonic coupling mechanisms has been clearly highlighted thanks to their abilities to build original nano-silica-networks and the specific development of new filters based on resonant tunnelling effects between multi-nano-ridges.
