METHOD OF FABRICATING AN OPTICAL FIBER PREFORM USING MCVD AND NONLINEAR OPTICAL FIBER FABRICATED USING THE METHOD

摘要

Disclosed is a method of fabricating an optical fiber preform using a modifiedchemical vapor deposition method and a nonlinear optical fiber fabricatedusing the method, in which an impurity component is doped after both ends of aquartz glass tube are partially collapsed, so that an impurity doping processcan be stably executed and the doped quantity of the impurity component can beincreased. The method comprises the steps of: forming a cladding layer and acore layer in a quartz glass tube; partially sintering the core layer;partially shrinking both ends of the quartz glass tube, in which the claddinglayer and the core layer partially sintered are formed; and doping a sinteredportion of the core layer with an impurity component, so that the opticalfiber preform fabricated has a predetermined function.
