We report on recent advances made in fabricating photonic microwires from silica nanoparticles using evaporative self-assembly. Silica microwires up to 7 cm in length and widths as small as 10 μm were fabricated with rectangular cross sections. A model of fabrication is put forward and confirmed by experimental observation. A crude dependence on concentration for an idealised spherical droplet is explored. © 2012 SPIE.
