Abstract
Elements such as glass spheres (11) and optical fibers (30') are permanently bonded to aluminum surfaces (13) of substrates (12) by applying pressure along with energy to the interface of the element and the aluminum. For example, a glass sphere is bonded by pressing it against aluminum while heating the aluminum. As an alternative to heating, acoustic energy can be applied to the sphere along with the pressure. Glass optical fibers can be bonded to aluminum surfaces in the same manner.
