Abstract
Technologies for fibers with nanotechnology is disclosed. In the illustrative embodiment, a preform is 3D printed with one or more sacrificial cores and one or more hollow channels. The preform is drawn into a fiber, and one or more metal core(s) is inserted into the hollow channel during the fiber draw. The fiber is then heated, breaking up the sacrificial cores into balls through capillary action. The fiber can be etched, exposing the balls made up of the sacrificial cores. The balls can be selectively etched, exposing the metal core(s) of the fiber. Additional embodiments are disclosed.
