Microwires and nanowires have been manufactured by using a wide range of bottom-up techniques such as chemical or physical vapor deposition top-down processes fiber drawing. Among these techniques, the manufacture wires from optical fibers provides longest, most uniform robust nanowires. Critically, small surface roughness high-homogeneity associated with (OFNs) provide low loss allow use for new applications communications, sensing, lasers, biology, chemistry. OFNs offer number outstanding...
