Abstract
A ferrule for optical waveguides includes an exterior and an interior of the ferrule. The interior of the ferrule has a bore defined therein that is configured to receive an optical waveguide. Material of the ferrule is such that the material changes from the interior to the exterior of the ferrule, where the thermal expansion coefficient of the material transitions from less than 30×10−7/° C. at the interior of the ferrule to greater than 70×10−7/° C. at the exterior of the ferrule. The thermal expansion coefficient of the material may change by way of discrete layers in the material between the interior and exterior of the ferrule.
