Ultrafast Photonics: Graphene-Polymer Nanofiber Membrane for Ultrafast Photonics (Adv. Funct. Mater. 5/2010)

Loh and co‐workers demonstrate on page 782 an electrospun graphene–polymer nanocomposite that exhibits wideband saturable absorbance for laser pulse shaping. A freestanding, mechanically robust membrane which is composed of nanofiber network of graphene‐polymer nanocomposite is fabricated by electrospinning and applied as a mode locker in fiber lasers. The performance of these graphene‐polymer nanocomposites is better than single‐wall carbon nanotubes in terms of modulation depth and nonsaturable loss.
