<p>Disclosed is a method of fabricating an optical fiber preform using a modified chemical vapor deposition method and a nonlinear optical fiber fabricated using the method, in which an impurity component is doped after both ends of a quartz glass tube are partially collapsed, so that an impurity doping process can be stably executed and the doped quantity of the impurity component can be increased. The method comprises the steps of: forming a cladding layer and a core layer in a quartz glass tube; partially sintering the core layer; partially shrinking both ends of the quartz glass tube, in which the cladding layer and the core layer partially sintered are formed; and doping a sintered portion of the core layer with an impurity component, so that the optical fiber preform fabricated has a predetermined function.</p> |
