On-chip Multimode Opto-electronic Neural Network
Jinlong Xiang, Youlve Chen, Chaojun Xu +5
Opto-electronic computing combines the complementary strengths of photonics and electronics to deliver ultrahigh computational throughput with high energy efficiency. However, its…
Photo-thermoelectric and photoelectric contributions to light detection in metal-graphene-metal photodetectors
T. J. Echtermeyer, P. S. Nene, M. Trushin +8
Graphene's high mobility and Fermi velocity, combined with its constant light absorption in the visible to far-infrared range, make it an ideal material to fabricate high-speed and…
Ultrafast and widely tuneable vertical-external-cavity surface-emitting laser, mode-locked by a graphene-integrated distributed Bragg reflector
C. A. Zaugg, Z. Sun, V. J. Wittwer +11
We report a versatile and cost-effective way of controlling the unsaturated loss, modulation depth and saturation fluence of graphene-based saturable absorbers (GSAs), by changing…
2μm Solid-State Laser Mode-locked By Single-Layer Graphene
A. A. Lagatsky, Z. Sun, T. S. Kulmala +9
We report a 2μm ultrafast solid-state Tm:Lu2O3 laser, mode-locked by single-layer graphene, generating transform-limited~410fs pulses, with a spectral width~11.1nm at 2067nm. The m…
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…
