Abstract
In this paper, a polymer fiber was constructed by siphoning the xylene solution of a polymer into a capillary tube with 300 μm inner diameter. After the solvent evaporating, the polymer fiber was lighted by an external pump beam and the amplified spontaneous emission (ASE) of the polymer fiber is investigated. The emission spectra are recorded, and the intensity and the full width at half maximum (FWHM) as a function of pump power intensity are analyzed. The absorption coefficient of polymer F8BT is obtained from a polymer F8BT film with a thickness of 200 nm. For the high absorption of polymer, the pump beam can not penetrate the long F8BT fiber. The sketch up diagram and an optical photo show it in vividly. This fabrication method provides a cheap way for application of micro polymer fiber. Keywords: polymer fiber, amplified spontaneous emission, absorption coefficient
