Abstract
A method of securing an optical fiber to a ferrule involves heating the ferrule to cause thermal expansion. A ferrule bore of the ferrule increases in diameter as a result of the thermal expansion, and an optical fiber is inserted into the ferrule bore. The ferrule is then cooled so that the ferrule bore decreases in diameter and forms a mechanical interface with the optical fiber. Finally, the optical fiber is fused to the ferrule by irradiating the optical fiber and the ferrule with laser energy.
