Ultrafast nonlinear optical properties of bundles of carbon nanotubes

The optical properties of bundled nanotubes were examined for high-bit-rate telecommunication applications. The diameters of the nanotubes in the bundles were determined to be from 0.6783 to 1.5147 nm, and their chiralities were also determined using resonant vibration modes. Their crystallographic quality was examined using atomic-scale resolution microscopy. Then, we highlight this vicinity performing calculations to determine the intertube equilibrium distance. These simulations integrate van der Waals interactions between nanotubes. Ultrafast and efficient nonlinear absorption properties of bundled nanotube films produced using a simple process were demonstrated and compared with semiconducting quantum-wells.
