TI  - Fabrication of Carbon nanotube poly-methyl-methacrylate composites for nonlinear 
      photonic devices.
PG  - 11337-43
AB  - Carbon nanotubes (CNT) are an attractive material for photonic applications due 
      to their nonlinear optical properties, such as the nonlinear saturable absorption 
      and high third order nonlinearity. However their utilization has been hindered by 
      the lack of flexibility on the device design which rises from the current methods 
      of Carbon nanotube deposition within the optical system. A suitable approach to 
      solve this problem is to embed the CNTs in an optical material from which complex 
      devices such as optical waveguides or optical fibers can be fabricated. Here, we 
      propose a novel method to fabricate Carbon nanotube-doped 
      poly-methyl-methacrylate (PMMA) composites in which the Carbon nanotubes are 
      dispersed in the methyl-methacrylate (MMA) monomer solution prior to and during 
      the polarization process. This method allows the bundle separation and dispersion 
      of the CNT in a liquid state without the need for solvents, hence simplifying the 
      method and facilitating the fabrication of volume CNT-PMMA. Volume fabrication 
      makes this technique suitable for the fabrication of CNT-doped polymer fibers. In 
      this paper, we also analyzed the merits of adding dopants such as diphenyl 
      sulfide (DPS) and benzyl benzoate (BEN) to the CNT-PMMA composite and we observed 
      that DPS plays the role of CNT dispersion stabilizer that can improve the device 
      performance. The CNT-PMMA composite was employed to implement passive mode-locked 
      laser.
