摘要:
A method for fabricating a fiber with optical cores of diameters between 2 to 20 microns is depicted. A first step includes the fabrication of a step-index preform of predetermined dimensions. The preform is drawn into a conventional fiber by conventional techniques resulting in a fiber having an outer diameter of about 120 microns or larger. The fiber is then emplaced in a glass tube. The tube is collapsed on the fiber by heating the same resulting in a second preform. This preform is again drawn into a fiber by conventional techniques to obtain a final fiber having core dimensions indicative of single mode operation with compatible outer diameters.
