We report on a technological route for the integration of large arrays of Ge nanowires (NWs) in a human hair like glass micro fiber, the length of the micro fiber reaching one meter. The route comprises (a) the formation of semiconductor microwire in glass insulation by capillary drawing from the bottom of a glass tube softened by a conducting Ge melt drop levitating in the high frequency electromagnetic induction field; (b) mechanical assembly of a bundle from equal length cut microwires which are distributed in a two dimensional quasi hexagonal densely packed lattice encircled by a joint glass envelope; (c) stretching of the obtained preform under proper heating conditions to reduce the diameters of the stacked together microwires; (d) repeating the cut assembly stretching processes for the purpose of further decreasing in transverse dimensions of constituents down to 150 nm. The fascinating incorporation of huge amounts of Ge nanowires in glass micro fibers opens new possibilities for the development of highly integrated photonic and quantum electronic systems.
