ABSTRACT:
An optical waveguide preform is fabricated by inserting a rod inside a tube and collapsing the tube. The inner diameter of the tube is adjusted before inserting the rod to provide a predetermined gap width between the inner surface of the tube and the outer surface of the rod. The gap width is selected as a function of the cross sectional area of the tube in order to minimize core eccentricity in the finished waveguide.
