Optical Fibre Nanowires and Related Structures

The fabrication of optical fibre nanowires by flame-brushing represents a top-down method to reliably manufacture the longest, most robust nanowires from silica and compound glasses. Small surface roughness and long-length diameter homogeneity provide the low-level of loss needed for optical applications. A considerable fraction of the transmitted power propagates in the evanescent field outside of a nanowire allowing the prompt fabrication of high-Q resonators and several sensors.
