Abstract
A method for fabricating a thermally expanded core (TEC) fiber including the steps of arc-fusion splicing two optical fibers having different clad outer diameters, and cutting boundary surface between an optical fiber having a small clad outer diameter and an optical fiber having a large clad outer diameter of the two optical fibers to obtain the thermally expanded core (TEC) fiber. Also, the method further includes the step of polishing the cutting face of the optical fiber having a small clad outer diameter of the two cut optical fibers.
