dc.description.abstractThe enhanced saturable absorption (SA) of a one- dimensional (1D) photonic crystal (PC) made from polymers and graphene composites by spin-coating is observed. It shows obvious bandgaps at two wavelengths in transmittance. Femtosecond Z-scan measurement at 515 nm and 1030 nm reveals a distinct enhancement in the effective nonlinear absorption coefficient βeff for graphene nanoflakes embedded in the PC, when compared with the bulk graphene-polymer composite. The effect is studied in a wide range of laser intensities. Graphene inclusion into a 1D-PC remarkably decreases the SA-threshold and the saturation intensity, providing a desired solution for an advanced all-optical laser mode- locking device.en
