Graphene Q-switched, tunable fiber laser
D. Popa, Z. Sun, T. Hasan +3
We demonstrate a wideband-tunable Q-switched fiber laser exploiting a graphene saturable absorber. We get ~2us pulses, tunable between 1522 and 1555nm with up to~40nJ energy. This…
Sub 200fs pulse generation from a graphene mode-locked fiber laser
D. Popa, Z. Sun, F. Torrisi +3
Ultrafast fiber lasers with short pulses and broad bandwidth are in great demand for a variety of applications, such as spectroscopy, biomedical diagnosis and optical communication…
Graphene Photonics and Optoelectronics
F. Bonaccorso, Z. Sun, T. Hasan +1
The richness of optical and electronic properties of graphene attracts enormous interest. Graphene has high mobility and optical transparency, in addition to flexibility, robustnes…
Wideband tunable, graphene-mode locked, ultrafast laser
Z. Sun, D. Popa, T. Hasan +5
We report a tunable ultrafast fiber laser mode-locked with a graphene saturable absorber. The linear dispersions of the Dirac electrons in graphene enable wideband tunability. We g…
