Carbon nanotube–polymer composites for photonic devices
نویسندگان
چکیده
We report the fabrication of high optical quality single wall carbon nanotube polyvinyl alcohol composites and their application in nanotube based photonic devices. These show a broad absorption of semiconductor tubes centred at 1.55mm, the spectral range of interest for optical communications. The films are used as mode-lockers in an erbium doped fibre laser, achieving 700 fs mode-locked pulses. Raman spectroscopy shows no damage after a long time continuous laser operation. r 2006 Elsevier B.V. All rights reserved. PACS: 42.55.Wd; 42.60.Fc; 78.67.Ch

Nanotube and Graphene Polymer Composites for Photonics and Optoelectronics
Polymer composites are an attractive near-term means to exploit the unique properties of single wall carbon nanotubes and graphene. This is particularly true for composites aimed at photonic and optoelectronic applications, where a number of devices have already been demonstrated. These include transparent conductors, saturable absorbers, electroluminescent and photovoltaic devices. Here, we pr...

متن کاملFabrication of Carbon nanotube poly-methyl-methacrylate composites for nonlinear photonic devices.
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 app...
