    Abstract: PURPOSE:To improve the productivity of a polarization keeping fiber, easily, by increasing and decreasing the flow rate of the dopant gas, vapor of core material, or vapor of clad material supplied to a burner at every turn of the target by 90 deg.. CONSTITUTION:The multiplex tube burner 5 is supplied with SiCl4 gas and GeCl4 gas from the raw material supplying system 6, and at the same time, with a combustible gas and O2 gas from the flame gas supplying system 7 to synthesize the soot 10 by the hydrolysis reaction in the flame. The soot is blasted and deposited to the lower end of the quartz rod 1 by the burner 5. Since the quartz rod 1 is pulled up while being rotated at a constant speed with the motor 2 controlled by the controller 4, the core part is formed to the end of the quartz rod 1 along its axis. Separately, SiCl4 gas, BBr3 gas, a combustible gas, and O2 gas are supplied to another multiplex tube burner 8 to synthesize the soot 11 by the hydrolysis reaction in the flame, and the soot is blasted with the burner 8 horizontally to the lower end of the quartz rod 1 to form the clad part deposited around the core part. The objective preform can be manufactured by this procedure.
