Design and fabrication of semiconductor optoelectronic fibres. (IMAGE)
Caption
a) Schematic of the molten-core method: a glass cladding (purple) and semiconductor core (black) preform is drawn into fiber dimensions. b) Fibre core geometries and capillary instability: Schematics (left) and optical images (right) showing different degrees of instability. Scale bars, 100 μm. c) Fibre core geometries under stress: Schematics (left) and optical images (right) showing intact and cracked cores. Scale bars, 100 μm. d) Continuous semiconductor core fiber: One drawing process yields about 100 meters of fiber, with glass cladding removable by acid etching. e) Convergence fibre drawing technique: Semiconductor fibers and metal wires maintain solidity, forming intimate interfaces in the necking region.
f) Functional fabric: Enabled by the resulting optoelectronic fibers.
