The wires have cross-sectional dimensions from less than 100 nm to about 1 mu m, depending on the duration of the treatment, and lengths of up to about 2000 mu m. Waveguide behaviour of the wires was demonstrated for visible light, which shows the potential applications of these structures for optical nanodevices. eng open access High aspect ratio GeO_2 nano- and microwires with waveguiding behaviour journal article
