Wavelength tunable soliton rains in a nanotube-mode locked Tm-doped fiber laser
B. Fu, D. Popa, Z. Zhao +4
We report soliton rains in a tuneable Tm-doped fiber laser mode locked by carbon nanotubes. We also detect their second- and third-harmonic. We achieve a tuneability of over 56nm,…
Scalar Nanosecond Pulse Generation in a Nanotube Mode-Locked Environmentally Stable Fiber Laser
R. I. Woodward, E. J. R. Kelleher, D. Popa +5
We report an environmentally stable nanotube mode-locked fibre laser producing linearly-polarized, nanosecond pulses. A simple all-polarization-maintaining fibre ring cavity is use…
Graphene Phase Modulator
V. Sorianello, M. Midrio, G. Contestabile +7
We demonstrate a 10Gb/s Graphene Phase Modulator (GPM) integrated in a Mach-Zehnder interferometer configuration. This is a compact device, with a phase-shifter length of only 300$…
Ultrafast pseudospin dynamics in graphene
M. Trushin, A. Grupp, G. Soavi +8
Interband optical transitions in graphene are subject to pseudospin selection rules. Impulsive excitation with linearly polarized light generates an anisotropic photocarrier occupa…
Few-cycle pulses from a graphene mode-locked all-fiber laser
D. Purdie, D. Popa, V. J. Wittwer +6
We combine a graphene mode-locked oscillator with an external compressor and achieve~29fs pulses with~52mW average power. This is a simple, low-cost, and robust setup, entirely fib…
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…
