We present a simple and inexpensive way to incorporate nanostructures in optical fibers based on optically driven transport of nanoparticles. The technique has been previously used to incorporate carbon nanotubes in fiber laser systems and relies on the deposition of nanostructures driven by the optical radiation propagating in the fiber. We demonstrate that this technique allows for incorporating graphite nanotubes and nanoparticles on the tip of the fibers and fiber connectors. Flow visualization techniques and thermal analysis of the deposition process show experimental evidence of the thermophoretic and pressure gradients involved in the incorporation of nanostructures onto optical fibers. Furthermore, we demonstrate the formation of micron sized bubbles on the tip of the fibers coated with nanostructures and show that this technique could render useful for developing micro bubble generators and mixers for micron sized structures.© (2010) COPYRIGHT SPIE--The International Society for Optical Engineering.
