WANG2020-06-042020-06-042011https://scholars.lib.ntu.edu.tw/handle/123456789/497247Propagation losses, transmission spectra and optical degradation attributed to surface scattering, crack propagation and water absorption were characterized for long microfibers fabricated by using a drawing tower. The propagation losses and optical degradation at 1550 nm wavelength were found increasing as the diameters decreased for the microfibers. A coating setup was established where polydimethylsiloxane (PDMS) was used as coating material and a CO2 laser as curing source to form a cylindrical film layer along the surface of microfiber. It was confirmed that no optical degradation was observed for the long drawn microfibers with protective coating over a long period of 18 h. © 2011 Elsevier B.V.
