Abstract :
Recent progress on the drawing of micro and nanowires shows the length could only reach several millimeters because of the lack of material feeding mechanism. We report here a multistage modified fiber drawing process which allows a fiber preform to be drawn several times in the heating zone so that the desired diameter of microns and nanometers can be achieved more than 1 m long. Current results show that by this approach the micro/nano optical wires (MNOWs) could be drawn with the length up to 165 cm and the diameter down to 1.9 mum. A real-time diameter measuring system is also developed to monitor the diameter in situ and hence to optimize our fabrication process.
