- An efficiently prepared graphene from a bulk graphite using mechanical exfoliation is
experimentally investigated for the first practical application to ultrafast photonics. Overcoming the
limitations of the method in its size and atomic layer control, the multilayered graphene guarantees
a nonlinear intensity modulation. After confirming its excellent crystal quality and few-layered
nanostructure employing Raman analysis and atomic force microscopy the graphene layer is
introduced into a fiber laser as an intracavity saturable absorber to realize the passive mode-locking
that produces picosecond pulses at the repetition rate of 10.9 MHz. Extinction ratio of the resultant
pulsed output is higher than 40 dB.
